[Gmsh] parsed post-processing file: interpolation between points

Does it mean I have to use "scalar triangle" (ST) and write an entry for
each triangle? Is the order of the 3 points defining the triangle
important?

I also have the topologicial information in a mesh file. Could the
information from the mesh and from the data be combined? (I think this
has already be discussed by Thomas Gazzola in a mail yesterday).

Thanks,
