[Gmsh] Postprocessing of high-order elements

[Martin Vymazal]

Hello everyone,

 I'd like to know what is the correct way of displaying a numerical
solution on mesh consisting of higher-order elements. I used a sample
code from the manual (see file attached to this email), but I'm wondering
about several things:
 - First of all, is it possible to make the faces of the triangle curved?

 - Second, why isn't the solution plotted so that it covers the whole area
of the triangle? It looks like the mid-nodes are 'misplaced'
