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.


Displaying Crank Angle for a Multi-cycle Simulation

Four stroke internal combustion engines have a cycle of 720 degrees. Many CONVERGE users want to see crank angle represented as values from 0-720. CONVERGE simulations may span multiple engine cycles, so you could easily end up with solution times from 0-3600 (for example). The following PyTecplot code will create Zone Auxiliary data with the “true” crank angle. The user can then display the value on the plot using &(AUXZONE[ACTIVEOFFSET=1]:Crank_Angle) […]

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)  […]

Running a Recorded PyTecplot Script Gives Error

Problem: When I run my PyTecplot Python script, I receive a TypeError, ValueError, KeyError, or AttributeError. However, I recorded this script from the 360 user interface, or wrote it using the current Pytecplot documentation, so it should be correct. What is causing this error? For example, running a recorded script using plot.fieldmaps(6,7,8,9,10,11) with PyTecplot 1.0 gives the following error: Traceback (most recent call last): File “C:\recorded_pytecplot.py”, line 17, in <module> tp.active_frame().plot().fieldmaps(6,7,8,9,10,11).mesh.show=False TypeError: […]
