Dear Tetsuo,
The standard way in GetFEM is to define a fem in the whole domain and use
/md.add_filtered_fem_variable/(name, mf, region)
where region is the boundary. This will select the degrees of freedom
whose shape function is non-zero on the given region.
You can either select the degrees of freedom yourself and use a
"partial_mesh_fem".
Best Regards,
Yves

Dear Yves
I'm searching to how to make MeshFem on left and right and top mesh
border region in user document, but I couldn't find it.
Where can I get information about that?
Thank you.
Best Regards,

Dear Yves
I could understand that model object have no restriction for mesh dimension.
I'll tried to use it. I will ask you a question if there is an uncertain point.
Thank you for your support and development. GetFEM++ is very useful.
Best Regards,
Tetsuo

Dear Tetsuo,
The ability to couple problems defined on meshes of different dimensions
is one of the strenght of GetFEM.
You can indeed handle meshes of different dimensions in a single model.
If you have some variables defined only on a boundary, you can add some
weak form terms on that boundary. If you have a different mesh there,
you can add the coupling terms using the interpolation transformations.
And if you want to solve some sub-parts of your model, in order for
instance to solve you global model in an fixed point way, this is also
possible to make some partial solve (you can disable some variables to
freeze them).
Best Regards,
Yves

Dear GetFEM++ project
Hello. Now, I'm making 2D mesh model which have 1D mesh model in LEFT,
RIGHT and TOP side.
I have to solve 1D mesh model and solve 2D mesh model by using 1D mesh
model result.
I know that GetFEM++ couldn't solve different dimension model in one
object. So I made 4 model object and tried to move 1D mesh model
object result to 2D mesh model object result. But, it is a little
bothering to take correspondence between 2 model object.
Is there any good way to solve the probelm?
Best Regard Tetsuo,
