Greek or special character in variable name or text

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 […]

Linking with frames Apply Settings to all Frames

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 […]

Skip vectors or scatter points

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.


2D Probe calculation

Problem: What process does Tecplot use for probing? Also for streamtrace placement contour labeling linear interpolation and polyline extraction in 2D. Solution: In two dimensions Tecplot interpolates for dataset values at the chosen point using bilinear interpolation. For triangular cells, this is a straightforward interpolation of the three nodal values of the triangle that encloses the point:1. Determine the triangle that encloses the chosen point. 2. Determine the weighting to […]

3D Probe Calculation

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 […]

Cannot find shared library

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.


Better interpolation results

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 […]

Add-on cannot be loaded.

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. […]

Banner flash but Tecplot doesnt open.

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.


Add streamtraces by IJK

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| […]
