[blockMesh] Unwanted internal Mesh in OpenFOAM, using blockMesh

nitishanand1989 · October 29, 2015, 07:41

Dear Foamers,

I am relatively new to OpenFOAM. I have been trying to generate a wedge mesh for sphere, however, I am getting some unwanted internal mesh elements generated. These internal Mesh gives negative volume to the elements.

If some you had a similar problem and know how to fix it, then please give me suggestions.

Attached are the Images from paraView.
