Problem: What process does Tecplot use for probing in 3D? Also for streamtrace placement contour labeling linear interpolation and polyline extraction in 3D. Solution: Tecplot determines the tetrahedron that the point is inside and then does a weighted average of the data set values at the four corners of the tetrahedron to get the values at the point. This method is not the most accurate – especially if your grid […]
Problem: When I try to start Tecplot I get the message: Cannot find shared library. Solution: Solution 1: Set or add to SHLIB_PATH to include /usr/lib/X11R5. (HP-UX 10.x: The system file locations are different.) Solution 2: We use 2 permanent links that seem to take care of all the main problems. Link /lib to /usr/lib and link /bin to /usr/bin.
Problem: How can I get better results from interpolation? Solution: Be sure your destination zone has a greater density of points than your original data set and that the destination zone is a good match for the region defined by your points. To create specially shaped 3D zones use one of the add-ons included with Tecplot 9.2 or later. See the documentation for Tetra Grid Extrude and Prism Grid. Axis […]
Problem: I wrote an add-on that runs fine on my machine. But when a co-worker tries to load it on his PC he get the message: Add-on xxx.dll cannot be loaded. (126): The specified module could not be found. Solution: 1. Make sure that the add-on is compiled as a release build. 2. Verify that the add-on dll is located in a directory which is in the current path. 3. […]
Note: Tecplot 360 EX is native to the Mac and doesn’t rely on an X Windows System. Download the latest release or get a free trial. Problem: XDarwin also won’t launch. Solution: Installing XDarwin is a two-step process. Be sure to install the patch after installing XDarwin.
Problem: I am creating an animation file with a macro but not all changes that I make to my plot appear in the animation. Solution: There are two possible solutions: For each plot change that should appear in your animation enter a $!RedrawAll command then an $!Export command. If you use any $!Drawgraphics commands be sure $!Drawgraphics = Yes is placed before the $!RedrawAll command.
Problem: Interactively I can specify streamtrace start positions by giving the IJK location within a zone. How do I do this in a macro? Solution: It is possible to define a streamtrace starting position using IJK coordinates in a macro if you use the $!GETFIELDVALUE command to get the XYZ coordinates for a IJK location. Heres some example macro code: ## These variables define the IJK starting position: $!VARSET |Istart| […]
Note: This should no longer be an issue for Mac. Download the latest release or get a free trial. Problem: Some Tecplot buttons are sticking (not working). Sometimes the buttons on the toolbar appear to be selected but don’t do any action. Solution: This is a current limitation. Click a different button then click again on the desired button.
Problem: When I try to load a file into Tecplot 9 I get this message: Binary file version newer than Tecplot version. Upgrade Tecplot or use an older preplot to produce the data. Solution: The binary file format has been changed with Tecplot 10. If you save a binary file from Tecplot 10 or create a binary file using the current TECIO then try to load the file in Tecplot […]
Note: In Tecplot 360 EX hotkeys can be viewed using the “Alt” key. Problem: Is there any way to add hotkeys to certain menu items so that I can bring them up without using the mouse? Solution: Add the following to /app-defaults/Tecplot: Tecplot*main_filenew_mbopt.accelerator: N This will work but the menu itself will not show the N character.
