[Gmsh] Prism second order element error

[Luca Verzeroli]

Hi,

I'm trying to generate a mesh with second order elements.

I managed to create this mesh


generating the external surface and then extruding the mesh inside.

This is ok using 1st order element. Using 2 order element the following 
warnig appears:

I looked at the mesh and I noticed this

instead of

as using the 1st order.

That element are prisms. Is there a problem with this kind of element?

I'm using Gmsh version 4.4.0
