meshing tetrakaidecahedron
 

Dear Fellows,

I have got somecomplicated 3D thin-walled geometry i.e. a tetrakaidecahedron. i am struggling with the mesh quality. In order to get high quality mesh, i tried high cell density but to no avail. I have tried free meshing, cut-cell method, hex dominant, none is working. Probably im doing something wrong. I m new to ansys as well.

Can anyone guide me on this? below is the link for a similar geometry.
