Orthogonal meshing for crash

Wisawanart

Hello

As the crash simulation will involve with the stress wave, therefore the orthogonality of each elements are necessary. Then,  In hypermesh, they have got some meshing options that consider about the orthogonality or not ?

 

Thank you for your answer

Hi Nut,

Quads only option as mesh type uses a subdividing routine that tends to generate more orthogonal quad elements. And also,by making flow to align option produces a more orthogonal quad dominated mesh.
