[Other] Missing BC in mesh conversion from Star-cd to OpenFOAM

piccinini · June 17, 2009, 12:00

Hello,

I've converted a mesh from Star-CD to OpenFOAM. No error is printed, but one boundary condition (stagnation) is missing in constant/polymesh/boundary.

Has someone else seen this?

This could only happen if you have no faces in that boundary in your Star model - could you please check.

Otherwise, all boundary faces get read and converted into boundary conditions.

Hi, hjasak

I do have cells assigned to that boundary condition. It's a case I've already run in Star-CD.

The conversion does not find my stagnation BC. I can provide you star.bnd and the resulting boundary file if you want to take a look (~1MB zipped, it exceeds forum maximum file size)

thanks
