If you are on macOS or Linux, you may know that PyTecplot does not work in batch mode unless the ‘tec360-env’ script is run or evaluated. While this is not a big inconvenience, and the full process is detailed in the PyTecplot documentation, some may want a way to avoid this entirely. For example, if you handle many users who want PyTecplot to “just work” without the user having to set anything outside their Python […]
Problem: I get an error when starting Tecplot 360 on Linux with SELinux. Solution: SELinux (provided with some Linux distributions) adds an extra layer of security. It can prevent Tecplot 360 from starting in some cases. If you see this error message: mprotect failed in ExecutableAllocator::makeExecutable: Permission denied Enter these two commands. They will create a new policy module that allows what was denied in tec360-bin and will install it […]
Problem: Certain remote rendering technologies (such as XRDP) fail to repair the drawing area when other windows are dragged across it. Solution: To properly repair the drawing area in these cases set the following command to YES or TRUE in the tecplot.cfg file: $!Interface ManuallyRepairDamagedDrawArea = [BOOLEAN]
Problem: I want to run LaTeX in Tecplot 360, however my LaTeX engine, MiKTeX, is giving me an error when I try to generate LaTeX. Solution: We see users on Windows, specifically with MiKTeX, encounter one of two issues. This article addresses both of these, so that you can get back to using LaTeX in Tecplot 360. Problem 1) I see an error with a path to ‘Temp’ directories: […]
When looking at geographical or ocean datasets, it is often desirable to analyze a non-linear path through the dataset and view a vertical cross-section created by the path. For example, above is the Boston Bay ocean dataset in the Getting Started Guide. This article describes how to get a vertical cross-section or ‘transect’ using a PyTecplot script we developed. While Tecplot 360 has a built-in tool for creating slices, […]
How do I calculate the mass-weighted average of a scalar through a surface? Mass weighted average can be obtained from the combined use of the function editor and two separate integrations. The mass weighted average is usually defined as: Thus, it can be computed by dividing the summation of the value of the selected variable multiplied by the absolute value of the dot product of the facet area and momentum […]
Are Tecplot products supported on Apple Silicon (aka M1, M2, and M3 chips)? Yes. Tecplot 360, FieldView, Tecplot Focus, and PyTecplot all run on Apple Silicon based machines. With the release of Tecplot 360 2025 R1, 360 is now native on mac ARM chips. If you are using a version of Tecplot 360 released before 2025, you’ll need Rosetta 2 to run x86 versions of Tecplot products. If Rosetta 2 isn’t […]
Question: How do I convert a cell centered variable to be nodal, or vice versa? Solution: This can be done by creating a new variable in the Specify Equations dialog (Data>Alter>Specify Equations). By using the new var location field, a new variable equal to an existing variable can be created with values stored in either location. For example, say a dataset has a cell centered variable named Velocity: To convert […]
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 […]
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. […]
