    Hi,

    Has anyone tried to generate polyhedral elements from Salome?

      Hi

      If by polyhedral you mean hexaderal elements, then the answer is yes.  By sweeping or extruding triangles and quads I have produced Prismatic and Hexahedral elements in Salome. The problem is that the extruding process takes every sub feature level and extrudes those as well, so then you get a load of new rods and quads within your solid element mesh.  I am told that the delete option works its way up thru the element element order heirarchy so that rods and quads are deleted, in turn, to leave the solid elements behind.  I have not tested this yet. Another way, I think, is to create groups at each level, then plot the rods and quads in their groups and then do an element delete. Then replot the solid group.
