Paraview has interactive mode option to select cells and points. Steps to create streamline from a given boundary face: Normals are used to avoid cracks between tube segments. For example, if the on ratio is 3, then the output will contain every 3rd point, up to the the maximum number of points.Ĭell Centers (CellCenters): Create a point (no geometry) at the center of each input cell. OnRatio: The value of this property specifies that every OnStride-th points will be retained in the output when not using Random (the skip or stride size for point ids). This filter is often used before glyphing. Mask Points (MaskPoints): Reduce the number of points. In prost-processors such as CFD-Post from ANSYS or STAR-CCM+ from Siemens, the 'contour' refers to a 2D plots on a specified plane or boundary surfaces. One important difference with respect to other post-processors is the way 'Contour' filter is defined in ParaView - here the contour filter computes isolines or isosurfaces using a selected point-centered scalar array. Stream Tracer Seeds a vector field with points and then traces those seed points through the (steady state) vector field. The glyphs may be oriented by a vector and scaled by a vector or scalar. Vector plots and streamlines filters: Glyph Places a glyph, a simple shape, on each point in a mesh. Set number format of the legend (color bar): Press the key again to deactive the ortho-control. Use the numeric 1 or 2 key to place the start or end point, Ctrl+1 or Ctrl+2 places at mesh point.ĭrag the endpoints: use x, y or z key to constrain to axis. Use the p key to place alternating points, Ctrl+p places at nearest mesh point. These filter connections form a visualization pipeline. Filters are attached to readers, sources or other filters to modify its data in some way. Paraview used filters which are functional units that process the data to generate, extract or derive features from the data. The mouse operations to navigate can be set as shown in the following image.ĭefault setting for camera projection, number of colors in contour plots However, this option is applicable to only steady state results. In ParaView, *.case file can be read with mesh toplogy as well as simulation result data. The option is to export the FLUENT or STAR-CCM+ data in Ensight (Gold) format, *.case file. Similarly, *.sim files from Simcentre STAR-CCM+ cannot be read directly into ParaView. ParaView has the option to read the ANSYS FLUENT *.cas file and it can read only the cas file, *dat files cannot be read or loaded. Partial arrays is a term used to refer to arrays that are present on some non-composite blocks or leaf nodes It is normally required to apply a Cell Data to Point Data filter. Due to this property, many filters may not be directly applied to cell-centered attributes. Note that cell-centered attributes are assumed to be constant over each cell where as attribute is only defined on the vertices in a node-centred variable. The image above describes node-centred (or point-centred) and cell-centred schemes. The tree starts with an input 'source' and filters can be added in in parallel or paralle/series sequence. It uses 'Source' and 'Filters' as post-processing operation. Individual surfaces are refered to as patched. ParaView follows concept of blocks which refers to fluid zone, solid zone, boundary names. pvbatch is also a Python interpreter that runs Python scripts for ParaView for batch processing. You can think of this as the equivalent of the paraview for scripting. pvpython is the Python interpreter that runs ParaView’s Python scripts in interactive or GUI mode. Wrappers exists for Java, Tcl and Python. VTK incorporates several other libraries to provide basic functionalities such as rendering, parallel processing, file I/O, and parallel rendering." Toolkit (VTK) provides the basic visualization and rendering algorithms. ParaView comes with a pvpython application that allows you to automate the visualization and post-processing with Python scripting. The platforms supported by ParaView range from single-processor workstations to multiple-processor distributed-memory supercomputers or workstation clusters. The size of the data sets ParaView can handle varies widely depending on the architecture on which the application is run.

or The Grotto, was originally created to “add in greater measure to the Masonic fraternal spirit the charm of radiant cheerfulness and to maintain within the fraternity an impetus of royal good fellowship”. It is Islam and also see the Shriners below.)Ī Freemason organization more commonly known as M.O.V.P.E.R. (Take note of the similarities in the head dress. M ystic Order of Veiled Prophets of the Enchanted Realm The Golden Cross is among the very few secret societies that treat men and women equally. Its members today are men and women from Indiana, Columbia, Tennessee and Kentucky who pledged to abstain from taking alcoholic drinks. Though it originated in England, the strength of this secret society lies in its New York chapter. Morgan organized the United Order of the Golden Cross to provide a means through which members can have a safe and economical method of getting life insurance policies. It is the earliest known English group to be founded based upon the iconography of the ancient druids, who were priest-like figures in Iron Age Celtic paganism. Today, this secret society uses the Masonic Fraternity as its model but accommodates both men and women.Ī fraternal organization founded in London, England in 1781 that still operates to this day. In response to the order, he proposed the formation of a secret society that would promote the advancement of rural life. Oliver Hudson Kelley organized the National Grange in 1867 following the order given to him by President Andrew Johnson to visit the southern United States and identify the war-ravaged areas that needed rehabilitation. This organization has historically been primarily devoted to protecting Catholic churches from anti- Catholic forces, and assisting Irish Catholic immigrants to get into America, especially those who faced discrimination or harsh coal mining working conditions. Organized in 1890 and is a fraternal circle of Irish Roman Catholics who uphold the values of friendship, charity and oneness among its members. They never felt anything other than weightlessness as they orbited the Moon. The astronauts who journeyed to the Moon never felt anything special as they traveled away from Earth and towards the Moon. This same principle works on extreme scales, too. The astronauts on board the International Space Station are accelerating towards the center of the Earth at 8.7 m/s², but the space station itself also accelerates at that same value of 8.7 m/s², and so there's no relative acceleration and no force that you experience. Again, it's that same consequence of free-fall at work here. NASA / ESA / ISS Expedition 37īut every astronaut up there, all the time, experiences this same sensation: that of total weightlessness. This applies even on the International Space Station, despite the fact that the gravitational force from Earth remains at ~88% the value it is on Earth's surface. 'up' or 'down' as there is on Earth, as the spacecraft and everyone on board accelerates due to gravity at the same rate. In outer space, even though all the masses in the Universe gravitate just as normal, there is no. At their elevation, the acceleration due to Earth's gravity is smaller than it is at Earth's surface: 8.7 m/s² instead of 9.8 m/s², a reduction of only about 12%. The astronauts on the International Space Station, for example, are a little over 400 kilometers (250 miles) above the surface of the Earth. This is just as true on the surface of the Earth as it is when you're flying (level) in an airplane at 35,000 feet: the object underneath you pushes you up with an equal and opposite force to the amount that gravitation pulls you down. There is a gravitational force accelerating you, but there's an equal-and-opposite force pushing you back. It's hard to believe because it's so counterintuitive, but what you're experiencing right now is an equilibrium state. That weightless sensation, believe it or not, is what you feel when gravitation is the only force accelerating you. As Hawking said, 'people need not be limited by physical handicaps as long as they are not disabled in spirit.' During the moments where the plane is in free-fall, everyone on board experiences the sensation of weightlessness. Stephen Hawking, back in 2007, took a zero-gravity flight to experience the feeling of. or - for the lucky few of us - the moment that the plane turns off its engines when you take a zero-gravity flight.the first second you leap into the air or jump out of an airplane, before air resistance becomes important,. the instant the "drop" occurs when you're on a roller coaster,.you drive too quickly up a hill the moment before you start going downhill again,.That feeling of being in free-fall is commonly known as the sensation "weightlessness." You feel it when: But without an object to push back against you and resist the force of gravity, you no longer have a normal force. A freely falling object still experiences the gravitational force, just like everything else in the entire Universe. public domainĪll of those counteracting forces go away, however, if you meet one condition: if you're in free-fall. If the surface that pushes back against the mass is removed, the sensation won't be one of acceleration, but rather one of weightlessness. The force of gravity (red) and the normal force (blue), which are equal and opposite forces, as they.

From then on they’re inseparable, r often joking that she got Wanda for Nat and not them self. Nat bringing Wanda her favourite stuffie to make her feel better before taking Wanda’s hand and bringing her into her cage (which is a big deal because it’s HER cage that master got especially for her) and protectively curling herself around Wanda, chin over Wanda’s shoulder and face practically smooshing Wanda’s face into the ground but Wanda doesn’t care because Nat’s forgiven her and she feels so safe and warm in Nat arms that she can’t help but start purring. Nat realising that her kitty is just tiny and sensitive and that she needs to be gentle with her. Until one night Wanda has a bad nightmare while r’s still out on a mission, Nat waking up to Wanda shaking and crying while curled up in her spot at the end of r’s bed. Wanda even tried to get Nat to play despite still being scared but Nat just ignores her. Wanda didn’t mean to get Nat in trouble she was just scared but now Nat won’t talk to her and spends most of her time either pouting or glaring at her. This gets Nat in trouble with r and from then on she decides she doesn’t want a kitty anymore, getting insecure and wondering why she wasn’t enough for her master. Wait what about kitty!Wanda AND puppy!Nat at first they don’t really get along - Nat’s always trying to get Wanda to play with her and at first she’s interested but then Nat gets too rough and makes Wanda cry.

Setting it up under windoze was relatively easy. It is a multi-user blogging system (I thought it reminded me of a site I'd used when I set it up and that is indeed what is using - no plug intended) If you are implementing new features, installing a new PHP-based app, or trying to locate a bug on your website, it is important to know which PHP version your web server is running before taking any steps.Movable Type isn't just a single perl script. By receiving error notifications quickly and accurately, you can improve the ability to troubleshoot PHP issues. This tutorial has provided you with multiple alternatives to enable and show all PHP errors and warnings. Likewise, if you’re using nginx, you can use that directory for the error log. You may substitute httpd for apache2 if needed. If you don’t have access to the file, you can edit the nf or nf file directly. To enable error logging, edit your version of the file and add the following: ErrorLog “/var/log/apache2/website-name-error.log” This log is typically stored in the /var/log/httpd/ or /var/log/apache2/ directory. htaccess file, you can edit the nf or nf file directly. htaccess file by adding the following: php_value error_log logs/all_errors.log For example, use the code snippet: How to Create an Error Log File in PHPĮrror logs are valuable resources when dealing with PHP issues. To turn off or disable error reporting in PHP, set the value to zero. In this example, the output displays all errors except for notice errors. To exclude a particular error type from reporting: This list contains all the predefined constants for PHP error types. Just separate them with the pipe | symbol. You can add any other error types you need.

This is an example of the correction in a text editor:Įdit. Then, edit the display_errors line to On. On Linux distributions, the file is usually located in /etc/php.ini folder. If you have set your PHP code to display errors and they are still not visible, you may need to make a change in your php.ini file. You can also use the ini_set command to enable error reporting: Edit php.ini to Enable PHP Error Reporting To enable error reporting in PHP, edit your PHP code file, and add the following lines: If you do not see errors, you may need to enable error reporting. Or, the cause may be more complex, such as calling an improper variable, which can lead to a fatal error that crashes your system. Even something simple can cause an error, such as using incorrect syntax or forgetting a semicolon, which prompts a notice. A PHP error occurs when there is an issue within the PHP code. As I said, it's black-on-black with the keyboard and trackpad, which can make it a little difficult to see if you don't have a lot of light. I touched on the trackpad and the keyboard a bit earlier in the review, but now let's talk about them in a little more depth. Music can sound pretty tinny if you turn the volume up too high, so while the speakers will suffice if you use them sparingly, you might want to invest in a good pair of headphones if you'll be playing a lot of music or watching a lot of video on the machine. Bass doesn't sound as hefty as it should out of the box, and though you can certainly crank up the volume on the Yoga 13's speakers, you might not want to. The speakers on the Yoga 13 are decent, but like the speakers on most ultrabook and laptops, they aren't anything to get excited about. The new controls obviously take some getting used to, but outside of that, I didn't have any issues playing Civilization V with the Yoga 13's touch screen – something to consider if you take the quality of a touch screen seriously. Though you wouldn't think that Civ V would be an ideal game to play with a touch screen, it actually worked out quite well, and that's a testament to how accurate the touch screen is. One interesting thing I noticed when booting up Civilization V was that it has been updated with touch controls for Windows 8. Still, the Yoga 13 performed well enough running Civilization V with most of the settings on medium (though a few settings had to be turned down to low), so you should be able to do some light gaming on this thing without any problems. The IdeaPad Yoga 13 comes equipped with Intel 4000 integrated graphics, so you're not going to have much a powerhouse when it comes to graphics ability. It will become your best friend before long. Luckily, Lenovo thought ahead and included that screen lock button I mentioned above – use it. One wrong move and you'll have the screen switching orientation on you, but that's one of the pitfalls of having so many different modes for the Yoga 13.

Undergraduate detox29 has found ChemSketch to be adequate and gxusm told me that they use Symyx Draw user, mainly because that’s what we were taught to use at University. Steven Bachrach of Trinity University is also a Symyx Draw user because of the “nice looking drawings, good structure to name facility, can produce InChIs, easy to use, free to academics, front end into many database systems.” “Symyx Draw is free for personal or academic use,” she adds. Also, structure and reaction cleanup options are not useful for aesthetics or minimizing space used.īut, chemical informatics expert Wendy Warr, tells me she uses Symyx Draw and its Structure Resolver too. However, the disadvantages are the price but for those who can get an institutional site license. It also has the ability to convert chemical names to structures and vice versa. “It’s pretty easy to figure out the basics, even for beginners,” she says, “but has many options available, like a TLC plate drawing tool, templates/clip art for conformers, glassware, complicated ring structures, and it’s easy to generate and modify figures quality and properties, save as multiple file types for publication. “But, as a physical chemist, I am deeply suspicious of anything with more than 10 atoms.”īiochembelle also uses ChemDraw. Littleghoti says he uses ChemDraw (despite the price), when he has to because it does all he needs. Feels a bit slower and clunkier than the others above. Doesn’t like lower case atom labels either. He adds that Chem ACX is another for looking for available chemicals, basically a ChemDraw type browser plugin, so similarities to that. Labelling atoms is easy, with a fixed list of the most common and a space to fill in your oddballs (it recognizes the elements too, though won’t let you type say zn for zinc, has to be Zn) Atom changes are straightforward too, as you click on the element you want and then just click everywhere you want it.” Then there is eMolecules, which is “mostly for looking for available chemicals, it has a very bare-bones interface, with one panel of tools, but it does the job and has very little load-up time as the Java starts. All the various rings are hidden away in “templates” but there is a lot to choose from, and simply drawing structures is easy. Perrey explains that with ChemSpider, “It seems like there are more steps to get down to drawing than there should be, but once you get there, the interface is functional but smooth. Atom-mapping is useful, but the auto-mapping is occasionally awful - better to do manually. I find it slow to get started, but once it is going, it is quite responsive and easy to use (except copy/pasting structures takes a while, sometimes easier to just redraw the product). “ChemDraw is perfectly fine, though I have a pet peeve that when I type an atom in lower case ( say n or cl) it fails to recognize that as the element I am putting in.” As far as the java apps go: Reaxys is the browser-based replacement for Beilstein, so I use it a lot. “I use ChemDraw for preparing Powerpoint slides or report figures, but most of the time when I am drawing structures (using a computer at least) it is doing literature searches and/or looking up information on chemicals that I am interested in using,” Perrey explains. Nevertheless, ChemDraw has good functionality, compatibility with colleagues, and produces “good looking drawings”.ĭavidperrey uses ChemDraw, as part of ChemBioOffice 2010, though says that he probably draws more structures using Java apps on ChemSpider/Reaxys/etc. Wozza told me that he uses ChemDraw, but hates how it’s broken on the Mac and lacks support for that platform, it’s also unfortunate that it has broken round trip editing, and poor cut&paste into other applications. The likes fo ChemSketch fair well and others such as Pymol and Symyx seem to be used by specialists in particular areas. The vast majority of users seem to side with ChemDraw, especially those in academia because of the liberal licensing, but they all gripes about compatibility and cutting & pasting. Sciencebase polled a few contacts via Twitter and LinkedIn to find out what chemical structure packages people are using, what are the pros and cons. Of course, with the likes of PubChem and ChemSpider now available one might wonder whether there is any need to draw one’s own structures from scratch, but plenty of chemists and others still do. Chemical structure drawing is of ongoing interest to chemists so we have a list of programs and reviews by users. |
