Running potentialFoam case with Gambit meshing
 

I'm trying to solve the case in tutorial, basic→potentialFoam→cylinder, which is presented in programmer's guide.

Everything is ok when I run the official code in tutorial.

However, solving problem appears when Gambit meshing is used.

1. Mesh is generated in Gambit v2.4.6 as if blockMeshDict does.

2. .msh file is imported into OpenFOAM with commend:
fluentMeshToFoam *.msh

3. Boundary file in polyMesh directory is rewrited.

4. Then I execute the program, problem appears.:(

What's wrong with my OpenFOAM?:(

Thanks in advance.:)
