The maintenance release 2026.2.0 of the EPPIC pre- and post-processing application is available for download.
September 2026 Release contains additional features:
New features:
- Faster loading of cases with multiple CGNS files. Adds an optional preference to prepare boundary surfaces on several threads — off by default, with a configurable thread count (0 = automatic).
- Gradients and integration as calculator operations. New rank-typed field-expression engine (scalar / vector / tensor aware) with vector operators (mag, dot, cosangle, …) and gradient scalars including helicity and normalized helicity; expression picker reorganised into operator groups; better validation of empty formulas, tensor results and gradient / parent errors; clearer variable delete confirmation.
- Vector arrows are now drawn on unstructured BC / wall surfaces.
Fixes:
- Fixed corrupted “Entire Window” screenshots and movies, and sharpened recorded animations: the movie bitrate now scales with the output size, the analyze panel placement / background / resolution are correct in captures, the double plot is gone, and the display-file dialog is asked once per case instead of once per file.
- ±X/±Y/±Z now snaps to a fixed orientation basis rather than a roll-preserving rotation.
- Windows packaging split into two separate installers — EPPIC and the RLM license server — with per-user install and licensing setup.
- Fixed the vector Project plane = Surface option, which used a component-wise multiply instead of a dot product, so the projected arrows were wrong.
License with CGNS module enabled will be issued to customers who paid for post-processing features.
