SnappyHexMesh hangs wile mesh refinement

Hi all,

after increasing the level of surface refinement higer than 4 snappyhexmesh hangs:

(gdb) where

If you have a testcase I can have a look at it.

Matthijs,

thanks for that offer. I will look what I can do for you. However it is very difficult for me to find the problematic regions of my geometry. Regards.

Dear all,

this plroblem has been solved with the lates development version. Thanks, great job.
