Cannot find font input file

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. […]

Solution: The difference between Tecplot 10 and Tecplot 9 is that different contour levels are set. Notice what levels Tecplot 10 sets set the same levels in Tecplot 9 and see if that makes Tecplot 9 performance slower. If […]

Animating points

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 […]

Blanking a corner of plot

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, […]

Multiple contour legends

Problem: I am using multiple contour variables C1 C2 C3 and C4 in my plot but I can only see the legend for C1. Solution: You must have the Contour Details dialog set to the desired contour variable (C1 C2 C3 C4) when you toggle on the Legend. And that contour variable must be in active use in the plot. If a variable is assigned to a Zone Layer like […]

Alt key does not work on Mac

Problem: The keyboard functions that require the Alt key do not work on Mac Solution: This is because Apple’s X11 X server does not treat the Command or the Option key as an Alt key (despite the fact that the Option key also says alt on it). The workaround is to add the following command to file /etc/X11/xinit/xinitrc: xmodmap -e keycode 63 = Alt_L This will make the Command key […]

Can a layout file created in Tecplot 10 be loaded to Focus?

Problem: Can Focus load a layout file created with Tecplot 10? Solution: Yes. In most cases, Focus will load a layout file created with Tecplot 10. If the data the layout file was created from was loaded via the Fluent loader or Plot3D loader or CGNS loader then Focus will not be able to load the layout because those loaders do not exist in Focus.
