hi ,
i have a piece from solidworks , a little bit complex,it define the fluid , and as i know hexaedral is a good mesh of the fluid , and in a next step i need to use layering method for the dynamic mesh , so i used mutizone method (quad meshing) but i get always "multi zone blocking decomposition failed"
i decreased meshing size and i used balayage method but always getting the same problem!
