Display Solution Time on Plot

Problem: I want to display the solution time on my plot.   Solution: Use dynamic text to refer to Tecplot’s SOLUTIONTIME variable. Navigate to the Insert>Text menu and click on the plot to open the Text Details dialog. Refer to the SOLUTIONTIME variable using the following syntax: &(SOLUTIONTIME) Please see the User’s Manual for a list of available options regarding dynamic text formatting. For example, to format the solution time […]

Clip Plane

Problem: I want to perform a clip plane.   Solution: Use a set of macro commands to clip above/below the defined slice.   The macro command related to the clipping of planes is: $!SliceAttributes 1 ClipPlane. It can take the following arguments: AbovePrimarySlice, BelowPrimarySlice, and None. Consider adding these macros to your Quick Macro Panel  for faster access: $!MacroFunction NAME = “Clip above primary slice” ShowInMacroPanel = TRUE $!SliceAttributes 1 ClipPlane […]

Convert Solution Time Format for Display

Problem: My solution time is in seconds (ssss.ss), and I want to display it as hours:minutes:seconds (hh:mm:ss.ss). Solution: Use a Tecplot macro to loop over time and retrieve the solution time. Assign the hours, minutes, and seconds to new variables and refer to their max values using dynamic text.   Macro Procedure (see link to the GitHub script below): Retrieve the number of time steps: $!EXTENDEDCOMMAND COMMANDPROCESSORID=’extend time mcr’ COMMAND=’QUERY.NUMTIMESTEPS […]

Extract Boundary Layer Values

This article describes both a macro and a PyTecplot script that extracts a field variable along a line normal to a surface. We recommend using PyTecplot insofar as possible. Example: Load the M6-Wing example file, which can be found in your Tecplot Installation Directory: …/Tecplot/Tecplot 360 EX 20xx R1/examples/OneraM6wing/OneraM6_SU2_RANS.plt. To better visualize the node at which we’ll probe, let’s turn on the mesh for the second zone. Zoom somewhere on […]

Offsetting an Axis in 3D Cartesian Mode

Problem: I am displaying one axis in my 3D plot, but my data interferes with it (see Figure 1). How do I offset my axis away from my plot? Solution: Change the minimum value of the vertical axis range in that view. In the case of Figure 1, the Z axis range minimum needs to be decreased. For this example, 1) Go to Plot>Axis… and select the Z axis and […]

Displaying Data Labels at High Magnification

Question: At high magnification, my cell and point labels become grainy and look terrible. How can I display these labels correctly? Solution: Use software rather than hardware rendering to display these node labels on a highly zoomed plot. See Figure 2. 1)  Download software_hardware_rendering_qmp.mcr  from our GitHub or create a macro with this code: #!MC 1200 $!MacroFunction Name = “SwitchToSoftwareRendering” SHOWINMACROPANEL = true $!Page UseSoftwareRendering = true $!EndMacroFunction $!MacroFunction Name […]

Using Data Skip to Approximate and Render a Large Dataset

Question: I am running out of memory rendering my fine-mesh data. How do I read-in a smaller, decimated version of my ordered dataset into my layout? More details: If you are working on a computer with limited resources, some processes can surpass the available computer memory. If you are unable to add more RAM, this can cause Tecplot to slow or, at worst, crash. Try this solution if some actions […]

Changing a Contour Legend Variable Name

Question: How do I change the name of a variable in the contour legend box? See Figure 1. Solution: Renaming a contour variable requires altering the variable name in the Data Set Information dialog box: 1) In Tecplot 360, go to Data>Data Set Info… (see Figure 2). 2) Double-click the name of the variable displayed in the contour legend and replace it with the desired name. Voilà, the contour legend […]

Fix Contour Labels Location

Problem: When exporting a picture, the location of the contour labels changes: Solution: By default the image is rendered off-screen and implies a re-draw of the plot. There are two possible solutions:   1) Prevent the re-positioning of the labels when a redraw occurs: In the Contour Details dialog, in the Labels tab, toggle Generate automatic labels (with each withdraw) off.   2) Prevent the redrawing by using the on-screen […]

How to Show Invisible Frame Borders

Problem: I have multiple frames on the paper and I don’t want frame borders in my export. So I’ve turned off the option Show border in the dialog Frame>Edit Active Frame. At the same time I’d like to see an outline for all invisible frame borders to get a better idea how these frames are positioned and overlap on the page in the 360 EX session. This outline should not […]
