Support for macOS Big Sur

Both Tecplot 360 and Focus 2020 R1 are currently unsupported on macOS Big Sur (11.0) and will not run. If you’ve already updated to Big Sur and need uninterrupted access to Tecplot products, please use Tecplot 360 or Focus 2019 R1. The 2019 releases can be downloaded from our MyTecplot portal. We apologize for any inconvenience and are working to resolve this issue. Updated 11/16/2020.


Linux Remote Display Issues

Problem: I receive a GLX error when remotely displaying Tecplot 360 on my Linux machine. Solution: First be sure your graphics drivers are up to date from your graphics provider (i.e. NVIDIA, AMD, etc.). If that doesn’t solve your problem, it is likely an issue with Indirect OpenGL Rendering being disabled. On newer Linux systems, NVIDIA and others are no longer starting X11 servers with indirect OpenGL enabled. Indirect rendering […]

Setting Custom Color Maps as Defaults

Problem: How do I set a custom color map as my default color map for a contour group? Solution: This solution consists of two parts, moving the .map file to the colormaps directory and editing the tecplot.cfg  file. First, save the color map file containing your custom color map into the colormaps  directory. This directory is found within the Tecplot installation directory. It is possible, and acceptable, for this .map […]

Understanding and Automating Viewer Position Angles

Problem: How do I change the viewing angles Psi, Alpha, and Theta from the viewer’s perspective? Also, please help me understand how these angles are defined. Solution: Below is a diagram from the 360 User’s Manual describing how Tecplot defines Psi (Ψ), Theta (θ), and Alpha (α). The following exercise uses PyTecplot to change each of the three angles by 5 degrees and manifests the result after each step. 1)  […]

Adding a PyTecplot Script to the Quick Macro Panel

Problem: Can I play a PyTecplot script from the Quick Macro Panel (QMP) in Tecplot? Solution: Yes! This procedure describes how to add a PyTecplot script to your to your QMP using the Histogram.py (found in the python handy scripts of our GitHub): 1) Make sure PyTecplot is installed and updated, along with other modules used in your PyTecplot script (such as numpy). It is also recommended that you install the latest […]

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 […]
