Dear Umut, If your region is a part of a mesh (not a boundary), you can simply defines the mesh fem by setting a finite element method only on the element of this region. You can also define a mesh_fem on the whole mesh but specify the region to the assembly procedures (or to the brick if you use the new bricks in Getfem++ 4.0). The third mean is indeed to use a partial_mesh_fem object. However, the implementation in Getfem++ 3.1 is not efficient at all. The implementation in Getfem++ 4.0 has been simplified and optimized.
