v2512: OpenFOAM Community

A big Thank you to the following people who contributed to OpenFOAM.

Contributions: Merge requests

• Robert Perry: Improvements to shortestPathSet of leak path detection algorithm: MR#779 (merged).
  • Enhanced multi-processor robustness when sampling points are distributed across multiple processors.
  • Added cell search with perturbation for points near processor boundaries.
  • Ensured all MPI reduction operations are called by all processors to prevent hanging in processors to prevent hanging in high processor count scenarios.
  • Added fallback mechanism to find the nearest valid cell when the target cell is not found locally.
• Yann R: Fix the wrong Courant number output when using localEuler in rhoCentralFoam: MR#776 (merged).
• Christian Rohr: Add the frozenFlow option to simpleFoam: MR#770 (in discussion).
• Carsten Thorenz: Possible issues in cell-to-wall distance calculations in wall functions: MR#773 (in discussion).
• AMD: Reproducible agglomeration
