Common/known current issues

General issues

  • The library is not thoroughly tested against all decomposition methods yet. So, if you encounter problems related to load-balancing, try a different decomposition method (scotch and hierarchical are preferred).
  • There are verified issues of the Load-balancer with some specific boundary conditions. These usually must be fixed on the BC side.

Post-processing related issues

Reconstruction fails

See Issue #7

Issues with surface sampling

See Issue #10

Pre-processing related issues

Support for refinement from snappyHexMesh and friends

blastAMR has thin support for refinement history produced by other tools. Due to the differences in the way these histories are generated, full support is difficult to achieve so:

  • Use hexRefiner when you process your base mesh with snappyHexMesh if you want the refinements to count.
  • Delete cellLevel and pointLevel files from the polyMesh folder for blastAMR to consider all initial cells to be at level 0.

See PR #22

Some turbulence models are inherently incompatible with blastAMR for now

See for example Issue #5
