Currently the parametric information is stored like this: node_num x y z entity_id < dimension parameter ... > If entity_id == 0, no dimension and no parameters are given (there's no parametric info) If entity_id != 0, the next integer is the dimension of the entity (== the number of parameters that follow), followed by the parameters. > Another question is about mixed elements.

It is indeed, unless we allow non-conformal meshes. Cheers, Christophe > > Best regards, > Michael Scheerer > > ---------------------------------------------------- > Dipl.-Ing.
