Tecplot 360 2023 R2 Release

Release Date: December 14th, 2023

Tecplot 360 2023 R2 includes important new features and stability improvements.

  • Added support for 2D Log Plots. To use log scaling in 2D plots, ensure that Dependency is set to Independent and then toggle on Use log scale. Note that when using log axes in 2D plots, vectors will not be drawn. Also note that geometries are not drawn using log scaling.
  • Updated VTK file loader to support reading of VTI and VTP files [Linux/Windows only]. Check out our blog post about VTK file support in Tecplot products. 
  • Updated SZPLT loader to support loading multiple files simultaneously which have different sets of variables. For example, when loading separate surface and volume data files.
  • Updated SZL Server to support SSH keys generated on newer Linux systems (e.g. Ubuntu 22 & RedHat 9).

Additional Updates & Features

  • PyTecplot 1.6.1:
    • Updated .szplt file loader function, tp.data.load_tecplot_szl(), to append multiple SZL files with different variable sets so that the resulting data set contains all variables specified in two files by default. This also fixed a bug in tp.data.load_tecplot_szl() which would append variable data “by position” instead of “by name” – resulting variable values potentially being associated with the wrong variable name.
    • See the PyPI changelog for a full list of updates.
  • See all updates in What’s New in Tecplot 360 or our Release Notes (PDF)

Automation (PyTecplot, Macros and Add-ons)

How do I use PyTecplot, the Python API in Tecplot 360?
PyTecplot docs, videos and FAQs are all on a separate web page dedicated to PyTecplot »

Q: How do I export an image when I have hundreds of zones?
If you have hundreds of zones it can be time consuming to switch to each zone and export an image. Macros can be used here to automatically activate each zone in succession and export an image.

  1. Scripting > Record Macro,
  2. Activate a zone,
  3. Export image
  4. Stop recording.

Then edit the macro file using a text editor and encase the export and activate call in a LOOP and ENDLOOP. Check the Scripting Guide in our documentation for additional information about these commands.

Q: Will macros and add-ons be compatible with Tecplot 360 EX?
Newer Tecplot 360 versions are backwards compatible with earlier versions of Tecplot 360.

  • TecIO files are compatible with all versions of Tecplot 360.
  • Add-ons will have to be recompiled. They are source compatible, but the libraries will need to be updated.
  • Existing Macros are compatible with earlier Tecplot 360 versions. However, Macros created with Tecplot 360 2014 and later are not backwards compatible with earlier versions.
