Automatic Connection to a License Server When Starting Tecplot 360

Problem: I want Tecplot 360 to automatically connect to a license server upon startup in the GUI or in batch mode.   Solution: Tecplot 360 offers two methods to automatically connect to a license server: creating an environment variable or updating a license file. Automatically connecting to a license server is especially important with headless machines. See more details on these two methods in the sections below.   Method 1 […]

How to use RLM Failover Keys

To install RLM Failover keys on Tecplot or FieldView products, follow the steps below. The names of the license files differ between the products but the steps are the same. Setting up RLM Primary/Failover Servers Place the following file in the primary server’s RLM installation directory: tecplotlm.lic OR fieldview.lic Place the following files in the failover server’s RLM installation directory: tecplotlm.lic and tecplotlm_failover.lic OR fieldview.lic and fieldview_failover.lic Restart each RLM.

Tecplot 360 hangs during movie creation when running tec360 in the background

Problem: Tecplot 360 appears to hang at the end of movie generation running ‘tec360 &’ (running 360 in the background). This is a known issue with the FFmpeg executable, which Tecplot 360 uses to create movie files. Solution: Include ‘-nostdin’ to the AVI, WMV, or MP4 Format Options in your tecplot.cfg file to avoid a FFmpeg hang if you’re running tec360 on Linux in the background. For example: $!ExportSetup MPEGFormatOptions […]

How to run PyTecplot with Anaconda

Problem: I’m running into errors when I try to run PyTecplot scripts with Anaconda. Solution: PyTecplot scripts can be run with Anaconda installed after creating a new, streamlined, conda environment which does not include Qt dependencies. PyTecplot is dependent on an external package, Qt version 5.15.2 (as of 360 2021 R2) which conflicts with the version of Qt (5.9.x as of November 2021) included in the base conda environment. The […]

Creating Geometric Regions

A quick reference guide on how to create different geometric regions can be found at the bottom of this article. In Tecplot 360, users may need to create a geometric region to perform operations such as extracting or blanking data. For example, an internal combustion engineer may want to quantify the temperature within a certain radius of a spark plug. By generating a sphere region around the spark plug and […]

Troubleshooting Linux Crashes

Problem: I get a crash running Tecplot 360 on my Linux operating system. Solution: Note: The 2020 R1 release of Tecplot 360 introduced a change in the way Tecplot is rendered in mesa. See the Troubleshooting chapter of the User’s Manual for more information (also at the bottom of this article). We’ve written up some instructions for responding to Linux crashes. Please check these questions: 1)  Double-check that your graphics […]

Support for macOS Big Sur

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.


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) […]

Tecplot Chorus Cannot Open Tecplot 360 on Linux – Permission Denied

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 […]
