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, […]

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 […]

Average of XY Mapping

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 […]

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 […]

Banner flash but Tecplot doesn’t 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.


Animation is incomplete

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.


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| […]

Add HotKeys

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.


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 […]
