I'm currently working in a solid-shell element which creates 3D elements by extruding a 2D surface meshed by quadrilaterals or triangles, which results in hexahedra and prism elements.
As you know, hexahedra and prism elements result from the combination of line elements with quadrilaterals and triangles, respectively.
This extruding process allows to select independent interpolation orders for the quadrilateral/triangle part, set in GiD, and another order through the line, it ranges from linear to quintic.
According to the manual, we have these possible options:

And I would need something like this (don't play attention to the numbering):

So the top and bottom of the 3D element has the shape and order of the original 2D element, and the side walls have an arbitrary number of nodes.
Is there any way to postprocess this type of elements? So far I can only think of postprocessing them by dividing the element into many linear sub-elements so GiD can handle them.
