[Gmsh] Using ElementData from external file

[Max Orok]

Hi Raavi,

You can use the python API for this. Here is a short script that combines
two files and creates a third from their combined element data, aka
post-processing views.

Sincerely,
Max

# combine element data sections of two msh files
# assuming they have the same elements

# mxo 2019

import gmsh

# spin up gmsh
gmsh.initialize()

# open the two files at the same time
gmsh.open("first-data.msh")
gmsh.open("second-data.msh")

# getTags will have both sets of view tags
for tag in gmsh.view.getTags():
    # print tag
    gmsh.view.write(tag, "combined.msh", True) # True == append to existing file

# end gmsh actions
gmsh.finalize()
