[Gmsh] Gmsh to Paraview

[Serban.Georgescu at uk.fujitsu.com]

Hi Yosuke,

Glad to know you solved the problem.
The 0/1 issue was high on my list of possible issues, I think I bumped into that as well.

Cheers,
Serban

Hi Serban

Thanks for reply. 

I have already solved the issues myself. I thought there were element definition differences between Gmsh and Paraview, but the problem was a trivial.
I just forgot to start connectivity table from '0' for Paraview, a you know, Gmsh file start it from '1'. That's why whole vertex coordinate was shifted and created strange geometry.
