[mesh manipulation] RefineMesh tetrahedral

markc · April 18, 2008, 14:35

Dear Foamers,

Has anyone succeeded in using refineMesh on a tetrahedral mesh? I want to use this utility in order to use surface capturing refinement. I want to model free surface waves caused by ships. It seems very hard to create a mesh with hex when curved ships hulls are involved.
However, if I am right, refineMesh only works on hex meshes. At least I just tried it on my tet mesh but checkmesh gave a lot of errors.

Is there any possibilty to model the water-air interface by some kind of moving/sliding interface?

Any help will be greatly appreciated.

Mark

Mathematically it does not seem very demanding to me. Add a point in the middle of a tet, add edges from this new point to old corner points etc. Or am I overlooking something?
However, I have no idea how to code this properly in C.

Hi,

I am also trying to use refineMesh on tetrahedral mesh. Have you succeded in doing that? If yes, can u give some hints?

Is mesh refinement of tetrahedral cells implemented in the new version 1.7.1?
