Dear Getfem++ Users,
I have the following bricks, in my assembled and working matrix, using MATLAB Interface
gf_model_set (md, 'add nonlinear generic assembly brick', mimLp, 'Grad_uv.Test_pv', -1, 0, 0);
gf_model_set (md, 'add nonlinear generic assembly brick', mimLv, '-pv.Grad_Test_uv', -1, 0, 0);
where uv and pv are two of the four unknowns of the system, and the mesh is a straight segment LambdaM defined as follows
Lambdaref= 0:1/(nbsk-1):1;
LambdaM=gf_mesh('cartesian', Lambdaref);
and mimLp and mimLv are the integration methods for pv and uv respectively over LambdaM.
This is running properly, my problem starts when I modify the mesh.
Instead of having one single segment I have a Y-shaped 1D mesh composed of 3 segments assembled by the 'add point' command. Every singe segment corresponds to a region.
I tried to implement the same code either over the single regions, either on the whole domain and in both cases I received the error "error in assembly string".
Do you have any idea of what the problem could be?
Thank you for your support,
Davide Manfredo
