Tecplot 360 2022 R2 Maintenance Release 1

Release Date: May 18, 2023

Updates & Improvements

  • Updated the Fluent Common Fluids Format (*.cas.h5/*.dat.h5) loader to support Ansys Fluent 2023 R1! If you’ve seen the following error loading 2023 R1 Ansys Fluent files in Tecplot 360, update to the latest release of Tecplot 360 to load Ansys Fluent 2023 R1 (*.cas.h5/*.dat.h5) files.
Fluent Load Error

Update to the latest release of Tecplot 360 to eliminate this error.

  • Updated the legacy Fluent loader (*.dat/*.cas) to better handle transient data with particle zones. In the 2022 R2 Maintenance release, solution times should be assigned correctly, and all particle zones should be grouped into the same time strand.
  • Updated the OpenFOAM loader to better handle surface data. This includes new support for boundary surface types such as zero gradient, symmetry, and wedge. In past 360 releases, surface zones of these types inherited values of zero for solution variables. After the update in this 2022 R2 Maintenance release, these OpenFOAM surface zones will inherit solution variable values.

    In previous versions of Tecplot 360, all the pressure values on the wing surface in the image below loaded in as zero values:
    Pressure Values had zero valuesIn the 2022 R2 Maintenance Release, pressure values are now nonzero on this wing surface:
    Pressure Values Nonzero

  • In addition, updated the OpenFOAM loader to hide non-wall boundary surfaces by default on first load so that surface zones of interest can be quickly visualized (these surface zones can be shown in the Zone Style dialog). For previous releases, OpenFOAM data sets showed all surface zones by default. In the image below, you can see the boundary surface zones shown on first load (covering the wing surface from view):
    OpenFOAM Showed All Surface ZonesAfter the update, the boundary surfaces from the previous data set are hidden on first load, revealing only the wing surface by default:
    OpenFOAM Shows Only Wing Surface
  • Updated the CFX loader to now support CFX 2023 R1.
  • Updated the ABAQUS loader to now support ABAQUS 2023.
  • PyTecplot: The supported Python version is now 3.9+ in PyTecplot 1.5.2. See the Python version support section.
  • PyTecplot: Documentation improvements.
  • Updated the FreeType third party library to 2.13 to address open source software security concerns.
  • Documentation improvements.

Tecplot 360 2022 Release 2

Release Date: December 14, 2022

  • PyTecplot ‘batch-packs’ are now available as a new licensing option (contact sales@tecplot.com for pricing). This option will allow an individual user multiple ‘batch’ instances while only checking out a single license seat. This license option is particularly useful for HPC users, as individual users are guaranteed to have a specific number of PyTecplot batch instances during their job – decreasing the possibility of a PyTecplot job failing due to licenses getting checked out by other users.
    • For use on an HPC, we suggest using the job scheduler to ensure the number of jobs are limited to the number of license seats. See the documentation for the SLURM job scheduler (https://slurm.schedmd.com/reservations.html).
    • Each license seat will be guaranteed a specific number of PyTecplot ‘batch’ instances per user. If a license seat is unavailable when the job is launched, the job will be unable to acquire a license and fail.
  • Fluent Common Fluids Format (HDF5) loader has been updated to support Ansys Fluent 2022.
  • Improved CGNS loader performance for data files with multiple volume sections.
  • CONVERGE Output (*.out) files produced by GT-CONVERGE (from Gamma Technologies) can now be loaded into Tecplot 360.
  • (Windows only) improved startup performance on systems with unavailable printers. Some users who switch between networks (remote work to office networks for instance) reported increased startup times, upwards of 45 seconds, on networks where a printer listed in the machine’s printer settings was not available on that network.
  • (Windows only) a batch script (tec360-env.bat) has been added to Windows installs to more easily run PyTecplot with specific versions of 360.
