Hi Everybody!

I want to run a simulation where i want to specify certain boundary conditions on a small spot on one surface - different to the rest of this surface. Therefore i created the attached mesh.
First of all I get a common error "Number of edges not aligned with or perpendicular to non-empty directions". It has to be some edges on the outer rim of the spot, I dont know how to fix it. I also attached the blockMeshDict. Thanks for all suggestions concerning this problem.

In general: Of course I will run some mesh refinements later on, but has anyone experience with similar meshes and maybe some advices? As said, my aim is to specify a individual BC on the round spot. Maybe someone has a complete different idea?

Thanks in advance!
