[Gmsh] Area/Volume of physical groups

[Max Orok]

Hello Johannes,

Volume case:
I think you can use the Plugin "MeshVolume" for this, calling it through
the plugin API interface.

Here is a link to the implementation:
https://gitlab.onelab.info/gmsh/gmsh/blob/master/Plugin/MeshVolume.cpp

Surface case:
Perhaps you could use the Integrate Plugin? I think you would have to first
have to make a physical group of just the 2D boundary elements and then use
the integrate plugin with a value of 1 (see discussion in link for more
info)

I hope this helps!
Max
