Hi all,
I am solving a 2D Poisson equation using command prompt. I have to apply a non uniform charge distribution over an area (e.g. a rectangular strip). So my rectangular strip is subdomain '1' and everything outside is '0'.
To be able to give a non-uniform pde coeff., I figured this out from the help "A row vector of values at the triangle centers of mass".
It seems obvious that the row vector should have a length equal to the number of triangles.
I initially tested my setup with a constant zero charge density:
u=assempde(b,p,e,t,1,0,0);
With this I get a solution.
To test the option of giving a row vector equal to the length of 't', I tried:
u=assempde(b,p,e,t,1,0,zeros(length(t)));
However the command prompt just hangs up with this command.

Any guidance is greatly appreciated.
