Re: [Getfem-users] [Getfem-commits] What is the best way to add parameter for each direction in term?

[Yves Renard]

Dear Tetsuo,

If I understand well, you need probably a matrix, not a vector

model.add_fixed_size_data("rho", bgeot::multi_index(2, 2));
model.set_real_variable("rho")[0] = rho_for_x;
model.set_real_variable("rho")[2] = rho_for_y;

getfem::add_linear_term(model, mim, "(rho*u).Test_u", TOP);


Best Regards,

Yves
