I am trying to import a StarCD mesh using starToFoam.
Because I have to specify a faceZone my idea was to create an internal boundary in my star mesh and then using the setSet utility to define my faceZone.

But the following errors show up when I am trying to import the mesh with the internal boundary.

void starMesh::createPolyBoundary(): Problem with face: 4(3643 3644 3716 3715)
Probably trying to define a boundary face on a previously matched internal face.
Internal face: 4(3643 3644 3716 3715)
PROSTAR Command: vset,news,vlis,3644,3645,3717,3716 $ bset,add,vset,all
void starMesh::createPolyBoundary(): Problem with face: 4(3644 3645 3717 3716)

Internal face: 4(3644 3645 3717 3716)

void starMesh::createPolyBoundary(): Problem with face: 4(3715 3716 3720 3719)

Any ideas how to fix this or how solve my problem?

I haven't looked at this yet, but it would appear to be orthogonal to the baffle treatment - ie, not impossible, but would take some time to implement.

If your desired faceSet is not too wild, you could try just using the cell table types information to segregate the mesh. For example, assuming that your faces are between ctype 1 and ctype 2, create cellSets based on the cell type, and create a faceSet that intersects both (setSet is good here) and finally use setsToZones to create the zones.

Hi Mark,

Greetings!!!

I am trying to solve a problem which involves a compressible flow in porous media with heat transfer effects. My domain is completely filled with porous media i.e all the internal cells have a porosity of 0.6. I imported the mesh from starCD by "star4ToFoam", but the imported OF mesh didn't detected the porous region. I guess I should do some editing in *.inp file to specify all the internal cells as porous, but if it is so, I don't know the format of this file. Could you please help me on this.
