Dear Cristian, You have several possibilities to define a coefficient whose value is different from a mesh region to another. If it is piecewise constant you can describe it on a P0 finite element method then you can obtain the degrees of freedom of a particular region with mf.basic_dof_on_region(rg). With the high level generic assembly, you can define a non-constant coefficient in a more general way by it expression with respect to X, the current position on the mesh (for instance sin(X[1]) + cos(X[2]) is valid).
I hope it could help you. Yves.
