Re: [Getfem-users] Position dependent elliptic problem

[Arvind Ajoy]

Hi Mattia,

Try the following to set A = cos(pi*x) in a 1-D problem.

A = gf_mesh_fem_get(MFU, 'eval', {'cos(pi * x)'});

Good morning everybody,
first of all I'd like to thank people reading and suggesting solutions
in this list: I always found a solution for my trivial problems!
I have to set a position dependent 'A' parameter in a 'generic elliptic'
problem. I think I have to use this function and pass the 'A' parameter
as 'V'.

gf_mdbrick_set
<http://download.gna.org/getfem/doc/getfem_matlab/gfm_40.html#gfmdbrickset>(b,'param',
name, MF,V | V) : change the value of a brick parameter. V should
contain the new parameter value. If a meshfem is given , V should hold
the field values over that meshfem (i.e. its last dimension should be
gf_mesh_fem_get
<http://download.gna.org/getfem/doc/getfem_matlab/gfm_33.html#gfmeshfemget>(MF,'nbdof')

But my question is: "How to format this matrix? V"

Thanks a lot Mattia
