Naruto is on a distinguished road
Dear all,
My problem is quite strange in nature. I have been using pointwise v 16R3 for the last couple of months. Pointwise has released a new version "version 17". My lab has recently acquired the license of the newest release. Now comes the problem.

I am currently using a half cylindrical computational domain containing one single blade. After meshing this half cylinder, I rotate the whole computational domain and create a two bladed turbine. I am attaching a picture of the computational domain.

In pointwise I keep the solver Ansysfluent. I convert my mesh to a .cas file. Then I copy that .cas file to my linux machine and transfer it to OpenFOAM/polyMesh. Now here comes the problem. After converting the mesh into OpenFOAM I normally use checkMesh utility of OpenFOAM and the result is just crazy. I have been using the same procedure in pointwise v16 R3. It did not show any problem.
I am copying the error message below:

I am attaching the full cylindrical computational domain which is giving me error in OpenFOAM:

It was gained from this half cylindrical rotation:

I am really out of clue. I would appreciate any help
