[snappyHexMesh] multi-Region failed to split one of the regions

phsieh2005 · April 23, 2010, 12:34

Hi,

I have several solid parts. SnappyHexMesh meshed with the correct refinement level for all regions, but, one of the solid regions did not get split from the base mesh. I am wondering if anyone experienced something like this and has a solution for it?

Thanks!

Hi, check your blockMesh in paraview and load additional your stl cad files into it.

If a boundary of a blockmesh cell is too near to one of your cad boundaries, snappyhexmesh can't mesh it correctly and problems can occur.

You have to change your blockMesh segmentation or the possition of your cad file.

Maybe it helps, good luck.
