Kindly help me regarding this problem.
when i do the meshing then this error is generated.


Exception:

Hi

I see/saw this error (far less in V4 though) when I was meshing complex geometries, typically when the mesher had meshed all but a few parts, surrounded by other meshed entities, then the last meshing had problems to create a coherent mesh in the last volumes.

To get around, try to use edge meshes as seed, mesh from inside/centre outwards, in several steps.

meshing is somewhat an art ... ;)

Good luck
