Hello everybody, I just get started with getfem and have some questions. What I want to do is to couple several equations. A minimal example of that would be something like:
Div(a1 \grad u) + Div(b1 \grad v) =g1 Div(a2 \grad u) + Div(b2 \grad v) =g2 That with some Dirichlet condition on the interval [0,1] Now I managed to do something like this buy taking the non model framework and assemble some matrices with the asm elliptic tools and put these matrices together by "hand". What I am wondering now is 1) Is there a brick that I can tell that in my equation there are two variables with a laplacian (elliptic) term? 2) If I would try to write this brick myself, would I have to do it in c++ (I am using the python interface) 3) Is there a way of assembling this without the model framework and without putting the matrices together "by hand" I would like to do all of this as time efficient as possible because in the end I want to solve time dependent problems with nonlinear terms. Thank you very much in advance , Franz Pichler _______________________________________________ Getfem-users mailing list [email protected] https://mail.gna.org/listinfo/getfem-users
