Both Tecplot 360 and Focus 2020 R2 are supported on macOS Big Sur (11.0); however, the 2020 R1 releases for these products do not support Big Sur. If you’ve updated to Big Sur and need access to Tecplot products, please use Tecplot 360 or Focus 2020 R2 or newer. Downloads can be found on the MyTecplot portal. Updated 12/14/2020.
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) […]
Problem: Tecplot 360 is unable to be opened from within Tecplot Chorus. I receive a “Permission Denied” error. Solution: First, be sure your permissions to the Tecplot 360 and Tecplot Chorus installation directories are allowed to read, write, and execute. Next, be sure the device’s shared memory file has open permissions as well (/dev/shm/). The /dev/shm/ file is where Tecplot Chorus’ boost libraries write to in order to share information […]
Question: What values can be changed in a Network License File? Answer: Below is an example of a network license file header. If your license file does not have a header like this.

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 […]
Problem: How do I find myhostids.txt licensing information for my host computer if I cannot share the myhostids.txt file created by Tecplot or FieldView software? Solution: This information can be procured from running a couple commands from the terminal. Instructions for both Windows and Linux are included below. Windows: On Windows, use the command prompt to get your hostname and ethernet physical address (12 digit number) using: ipconfig /all For […]
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 […]
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) […]
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 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 version of Tecplot […]
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: […]
