Hello,

I have a conjugate heat transfer problem, few electronic components being cooled directly by a fluid (immersion method of cooling) and i am using OpenFoam for this.

I have created the geometry and mesh in Salome software and was able to obtain the mesh in .unv format then using IdeasUnvToFoam, in openFoam.

Different cellzones corresponding to different solids were identified in a single ""cellZones" file in "constant" folder. Now i need to specify different thermo-physical properties for each solid such as cp, K, rho etc and need to give certain volumetric heat flux values to some solids. I am trying to use splitMeshRegions command to get different zones but not able to due to this error -" Build: _b45f8f6f58-20200629

Expected 0 arguments but found 1

See 'splitMeshRegions -help' for usage"

Thanks in advance for any help

Regards

1) You can create different mesh files and combine them with "mergeMeshes" in that way, they will be different regions, converting them to the cellZone with topoSet is easy.
2) You can directly use topoSet to define cellZone, but it is limited with simple geometric shapes(I think you can use stl file too but I haven't tried that).

Hi!


In salome create groups for every region and when you import the mesh, they will be in different cellZones, and you can simply use the "splitMeshRegions -cellZones -overwrite" command.
(At least it worked a few years ago like this, and I guess it still does.)

As above, use the commands:

IdeasUnvToFoam -writeZones
splitMeshRegions -cellZones -overwrite
