Dear Roland,

There is some basic automatic adaptation of mesh_fem and mesh_im objects to 
the refinement.

If the mesh fem has been initialized with a global method such as

mesh_fem::set_finite_element(pfem ppf)

or 

mesh_fem::set_classical_finite_element(dim_type fem_degree)

then the corresponding finite element will be set to all new elements.

It is also possible to directly call the method 

void mesh_fem::set_auto_add(pfem pf)

to specify the finite element for the new elements.


If you need something more adapted, you have to detect the newly created 
elements and set the finite element method.


The operations are similar for mesh_im objects.


Yves.
