Creating spherical domain for solving flow around a sphere
I am new to OpenFOAM and am using it to solve underwater implosion problems. I have been successful solving for flow around a spherical bubble of water in a large cubic domain using compressibleInterFoam. After a few oscillations instabilities start to creep in from the domain edge, I believe due to using a cubic domain outside of a spherical implosion.
I've been now trying to create a mesh of one octant of a sphere (with a hole in the center) using a hex block with two vertices collapsed onto other vertices. I am getting a fatal error saying "ill defined primitiveEntry".
Any help you all could give would be greatly appreciated! I haven't yet seen any posts about doing a spherical domain at all so maybe this is not the route to go.
