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, Tetsuo 2019年2月5日(火) 18:02 Tetsuo Koyama <address@hidden>: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.

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).

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?
