Error exporting mesh from SALOME to SU2

Use of the platform
1

Hi,

I’m trying to export a 3D mesh from SALOME to use in SU2 for CFD, but I’m running into errors.

  1. When I export directly to SU2 format, SALOME shows: “Export Failed: TypeError: Cannot unpack non-iterable CellBlock object.”
  2. If I export in CGNS format instead, it completes without errors, but SU2 fails to read it, showing: "Parsing config file zone 0, Assertion failed: head && *head file ../externals/cgns/hdf5/H5CX.c, line 3579.”

Is there a fix or workaround for this issue?

I had that kind of errors also when I tried to use directly the meshio suite, I think it is most likely a problem there. If I may suggest, I’d rather use the cfdmsh.py to export natively from SALOME to SU2.

I have been using the same script, but I often get the NPOIN mismatch error, especially while using viscous layers.
