Dear Tetsuo,

Your term

getfem::add_source_term_generic_assembly_brick(model, mim, "1.0*Test_u", TOP);

is a priori correct and should add a source term on the region TOP (Neumann condition), of course if the region is non-empty.

Apart from the fact that u is a vector field in your case, so that it should complain on the fact that "1*Test_u" is not a scalar. A correct expression should be for instance "[1,0,0].Test_u"

Best Regards,

Dear GetFEM++ Project

Hello. Thank you for your support. I could assemble the matrix in model object.
Today's question is that I couldn't build the rhs of equation.

I coded rhs's source_term_generic_assembly_brick by reading the
following document.
I added the source_term_generic_assembly_brick at line 432 for test.
But, the debugging output is zero in line 550. And the message's seem
not build the source_term_generic_assembly_brick.

I think my use it not correct. Could you teach me why it not work?
Thank you for reading.

Best Regard Tetsuo.
