Assigning faces or cells fro meshes created by distmesh

For example, I have generated a rectangular 2-D mesh with a cirlular objject embedded in the rectangle using "distmesh". Using geometryFromMesh (PDE toolbox), I can get the geometry and the mesh. However, the geometry variable only contains the the edges and one face, F!, and no information on the embedded object. I would like to apply different material properties to the two regions in my model. Without an identifier for the "face" of the circle, I am having diffiiculty trying to assign differnt properties to the two regions of my model. For 3D problems, this is even more of a problem in combining different geometries in the same model. How do I solve this problem when I obtain a geometry from a mesh created by other software packages.

Hello Lewis,
To get multiple subdomains into PDE Toolbox you need to use the four argument format of the geometryFromMesh. Like,
[g, msh] = geometryFromMesh(model,nodes,elements,ElementIDToRegionID)
Here, ElementIDToRegionID maps the elements to subdomains.
Regards,
Ravi
