Problem: I want to blank my contour plot only in the lower left-hand corner where x < 45 AND y < 30. Solution: You can use equations like the ones below to create a blanking variable equal to 0 only if x < 45 and y < 30. Then you can delete the extra variables {lowerx} and {lowery}. {lowerx} = max (x -45, 0) {lowery} = max (y – 30, […]
Problem: I have some files with some scatter points animated to move in constant velocity. However, the movie shows relative motion of the scatter points making the animation appear jerky. Solution: The reason the scatter points look like they are moving relative to one another has to do with the way they are drawn on the screen. Any object drawn to the screen will be rounded off to the nearest […]
Problem: In my XY Line plot, I want to show a line for the average value of one of the XY Mappings. Solution: You can have Tecplot calculate and plot the average for a line mapping: In the Mapping Style dialog Copy the line mapping and make sure the copy is shown. On the Curves page, set the Curve Fit for the new mapping to the General Curve Fit (One […]
November 2017 Update: LaTeX Fonts are available in Tecplot 360 2017 Release 3 and later. This gives you the ability to use your installed version of LaTeX to display complex formulae and equations directly on your plots. We test against MiKTeX and TeXLive but should be compatible with other LaTeX engines. Watch the LaTeX video tutorial Problem: Some variable names in my data file include one Greek character or another […]
Problem: I have several frames in my layout and I set the Within Frame Axis Style to be linked. Then I pressed the button for Apply Settings to All Frames. But when I change the label font for one frame te other frames do not change. Solution: Linking on the Between Frames page of the dialog will cause the changes in one frame to apply to all frames. Linking on […]
Problem: My data is very dense. I want to show vectors or scatter but not at every point. Solution: On the Zone Style dialog, go to the Points tab. One of the options is Index skip and this setting will apply to both scatter points and vectors.
Problem: I can create AVI files in my Tecplot product with the compression set to Lossless Uncompressed to play on a Linux or Macintosh platform but these files are very large. Is there a way to make them smaller but still able to play on these platforms? Solution: Yes. You can encode the uncompressed AVI files to MPEG4 which reduces the size to a fraction of the uncompressed size while […]
Problem: How can I calculate and display vectors normal to a surface? Solution: Load your dataset and then perform the following steps to calculate normal vectors in Tecplot 360 (not available in Tecplot Focus): Click on the Analyze menu and select Calculate Variables Select Grid K Unit Normal (vector) Set the New Var Location to Cell Center or Node, depending on the desired vector location with respect to the grid. […]
Problem: I have difficulty playing AVI animations created in my Tecplot product when I try to play them on my Macintosh or Linux platform. When I try to play them on my Linux platform the AVI files work with Xanim but Xanim itself does not work very well anymore. On a Macintosh platform, I use Quicktime but the AVI files that the Tecplot product creates do not open in Quicktime. […]
Problem: I tried to run Tecplot and got this error message when Tecplot tried to start up. What does it mean? Solution: This error message means that the environment variable that holds the path down to the Tecplot installation directory is not set correctly. That name of that variable depends on the product you are installing. For our latest products (2008 series) that variable will be called TEC_FOCUS_2008 or TEC_360_2008. […]
