Hello, I posted this question months ago and I still would be quite interested in an answer. Thanks Franz
>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
