Hey,

I want to create a quadrisected cylinder with blockMesh, like this:


What I've done so far is that I created a block with fewer than 8 vortices:



My question is, based on what do I have to define the 3 values in arc in the brackets, for example, arc 3 6 (? ? ?).

Thanks!

This is my blockMeshDict:
