Hi All,
I have always worked with snappyhexmesh alongwith blockmesh containing only hexahedral cells. But one of the demand that has come up from a customer is if I could use Prism cells instead of hex cells. My concerns are: 1. I saw on OPENFOAM user guide that instead of hex keyword, if I use prism, I can have prismatic cells. But my concern is that then the box itself would be a prism. I want to know if it is possible to have a cuboid as box and prism cells inside. 2. Suppose I find a solution to the first concern, is it then possible to work with prism cells in Snappyhexmesh? What parameters do I need to change for that? Thanks, Vneet |

Thanks for the clarification Bruno. You are right regarding prismatic boundary layer. My question now is,

sorry for the delay in responding. I thought of first using the mesh generated by snappy for solver and if the results are accepted by customer then if needed try cfMesh. It seems that he is more concerned with gradually increasing boundary layers and bigger cells in center than the prismatic boundary layer itself.
If I have to use cfMesh later and find any problems, I will continue the discussion. (or start another post) btw, is there any way to track my own posts? I see an option of "new posts" OR "your blog" but not "your post" Thanks Vineet |
