Tecplot 360 2021 R1 with Fluent® CFF HDF5 Support

BELLEVUE, WA (May 12, 2021) – Tecplot, Inc. has announced the general availability of Tecplot 360 2021 Release 1.

Tecplot 360 is the leading independent CFD post-processor in the industry and this release cements our commitment to being the best visualization and analysis tool for a wide variety of CFD simulation results.

The new Ansys® Fluent® Common Fluids Format (CFF) HDF5 file loader in this release saves Fluent users both time and disk space by reading their CFF data directly without a conversion step.  This allows Fluent users to realize other advantages of the CFF format such as it being faster for Fluent to write as well as file sizes being smaller.

“Ansys Fluent users have been asking us for Fluent CFF support in Tecplot and now we have delivered.  The ability to load this data will save Ansys Fluent users time, and would not have been possible without collaboration with our users and the support from Ansys staff.” says Scott Fowler, Tecplot 360 Product Manager.

“The HDF5-based CFF format gives our customers substantially improved I/O performance relative to our legacy file format, in particular for large cases using many compute partitions,” said Jeremy McCaslin, Ansys Manager of Fluids Product Management. “We are happy to see our software partners adopt our new CFF format to support our mutual customers.”

This release also includes support for Ansys CFX 2021 and Abaqus 2021 data files.  Other data loaders that received stability improvements include: OpenFOAM, Nastran, and various CAD formats.

For CFD code developers, we have seen up to an order of magnitude performance improvement to TecIO-MPI (parallel version of the TecIO library), which writes Tecplot SZL (*.szplt) files. Details of these performance improvements are in our TecIO Library.
