Hello everyone, for applyin
 
Hello everyone,

for applying a numerical integration algorithm in postprocessing, I need my fields on a tetrahedral mesh.
I thought of doing this by mapping the fields on a tetPolyMeshFaceDecomp-Mesh. Creating such a mesh is not the problem, but I don't know how to map my volVectorFields to tetPointVectorFields.
Is there a quick way of doing this? I found the tetPolyMeshMapper class, but I'm not sure if this could be applied.

Thanks, Hannes

Hannes, check these: - v
 
Hannes,

check these:

- volPointInterpolation class, and how it is used by the spray class to interpolate the cell center values at the lagrangian position

- fvMotionSolver, where the mesh motion calculated in a cell centre is then interpolated at the mesh points positions.

hope this can be useful,

regards

Tommaso

Thanks for the hint, Tommaso.
 
Thanks for the hint, Tommaso.

After analyzing the order of the points in the point list (built in "tetPolyMeshFaceDecomp::points()") it seems to me, that I just have to hook up the point-, surface- and cell fields after another to get the tetPointField.

Regards, Hannes
