[Gmsh] Geometry from an order 2 surface mesh

2018-06-01 Thread Jerome Robert
Hi all, I am trying to fill an existing order 2 3D triangular mesh with order 2 tetrahedron. In the result mesh, the order 2 vertices of my input mesh are all moved so they were linearly interpolated. So everything is as if my input mesh was used by gmsh as an order 1 surface. Here is my .geo:

Hi Jerome, Yes indeed - all our meshing algorithms currently generate 1st order geometrical elements, starting from 1st order geometrical elements on the boundary. The meshes are then "curved" later on. I will add the ability to re-use a given high-order discrete surface input when we curve to
