[Gmsh] Post processing higher oder triangles in GMSH

[Emayavaramban Elango]

Dear Gmsh, 

I am trying to post-process the plate element solution. The plate element that I am using has three dofs per node (w , - dw/dx , dw/dy ). But gmsh does not support writing angular displacement of a node in .POS file. To effectively visualize the plate, I wanted to interpolate the w (displacement) on midside nodes (3,4,5 for Triangle). But when I tried a sample .pos file having w_displacement only on midside nodes, it doesn't seem to be working.it shows zero displacement all over the element. I pasted the .pos file below. Please advise me to rectify this problem.

Any help would be greatly appreciated
