Dear All,

I am trying to import a 2D mesh from Gmsh containing 2 subdomains (physical groups) and their interfaces. I labeled the subdomains as “fluid” and “solid” in Gmsh. I’m using the command: mesh Th=gmshload(“Bone.msh”); . It works well and I can see the mesh . However i need to identify the different subdomains and their interfaces using their labels. How can i do it? you can see my mesh bellow.  
Thank you for any help

You can use `Th.region`. You’ll get two different integers for the two different regions.
