Tecplot 360ex & Chorus 2022 R2 (2022.2.0.18713) fixed

New Features & Improvements
- 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.
. 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 R2.
- 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.
- Documentation updates
Bug Fixes
- Fixed a crash when turning on plot approximations.
- Fixed a crash related to returning roaming licenses while disconnected from the license server.
- Fixed an issue on RLM license servers hosting multiple licenses on a single network license server. If there were multiple licenses on the network license server, the issue was that Tecplot 360 would not attempt to checkout license B’s seats when license A’s seats were reserved using the options file. This issue has been fixed.
- Fixed occasional crash when extracting slices when a slice group has multiple (start/end/intermediate) slices.
- Fixed an issue where OpenFOAM data files would not open if ASCII set files (typically located in ~/ constants/polyMesh/sets) were mislabeled as binary. Our OpenFOAM loader has always ignored set data and continues to, but that issue in the OpenFOAM data will no longer inhibit Tecplot 360 from loading. Please let us know if you are interested in loading the set data.
- The PLOT3D now correctly applies solution time to zones created by the existence of the FVBND file when loading function files. The PLOT3D loader previously applied solution time to function file zones but did not apply solution time to the FVBND zones.
- Fixed an issue where the ROMS data loader (included in the installation, but must be manually added to the tecplot.add file) produced incorrect V-Velocity values for K planes > 1.
- Improved EnSight Loader to load EnSight files produced by Star-CCM+. EnSight .case files with a 'time values' section are now treated as transient even if the 'time set' integer is missing from the 'model' and 'scalar per XXX' section of .case files.
- Fixed occasional hang when computing variables using Analyze>Calculate Variables on machines with high CPU-counts.
- Fixed an issue in Analyze>Calculate variables where “Normalize with Respect To” set to “Reference Values” or “Maximum-Magnitude” produced incorrect results for *.szplt data files.
- Fixed issue in which some variables could not be deleted due to Analyze>Calculate Variables incorrectly maintaining a ‘lock’ on variables used in calculations.
Build Changes
Tecplot 360 for Linux is built on CentOS 7.9 and uses the Qt 5.15.2 GUI toolkit. Due to this, you need to be aware of the following:
- On Linux, the SZL Server menu option File>Load Remote Data… may no longer show up in the File menu. If this is the case, make sure that you have libssh2 installed on your system.
- Tecplot 360 or PyTecplot may crash when remotely accessing a Linux machine due to insufficient OpenGL support via X-Servers. If this is encountered, use –mesa when running Tecplot 360 interactively and –osmesa when running Tecplot 360 or PyTecplot in batch.
Python version support
PyTecplot requires Python 3.7 or newer, due to an update of a third-party dependency (protobuf). The protobuf package is required to run PyTecplot in “connected” mode – that is, driving the Tecplot 360 user interface. PyTecplot may be installed without protobuf for batch only operation.
Tecplot’s Python support policy is to support the newest version of Python and the two previous versions. As of November 2022, we officially support Python 3.8, 3.9, and 3.10. Python 3.11 was released October 2022 and is expected to work with PyTecplot, but has not been fully tested yet. If you have issues with Python 3.11, we will do our best to support you.
