4. Updates Affecting Code Behavior

This section contains a list of changes that may cause the solution results from Ansys CFX to differ between Release 2025 R1 and Release 2024 R2.

  • The RGP Generator used internally by CFX-Pre generates tabular data with a different distribution of table cells. Although the new distribution improves the resolution of gas property values, more table cells are generated for a given interpolation tolerance. To compensate for the larger number of cells, the Low, Medium and High Table Resolution options for the Generate RGP File tool (see Generate RGP File in the CFX-Pre User's Guide) have been adjusted towards lower resolution. Compared to the previous release, for a given interpolation tolerance, the resulting table files are of comparable size and have similar or better resolution of gas property values.
