I believe I answered you privately, but I cannot find my email anywhere.
In case you didn"t receive it, I am sending such a test case here again.
The testcase is a box porous material model with 8 cells to be able to
interpolate BC's and to see the problematics clearlier. The confusing
thing might be the Time function, as I am working with the frequency
domain, but I simply used it artificially as a counter for frequencies
to generate a series of output files.
The problem appears in the pressure boundary condition, as I am trying
to force (250,0) complex-valued boundary values on certain faces. After
solving the system, the Dirichlet boundary values are not held, so
(250,0) becomes somewhat else.
Please, let me know, if some other information is required!
Maria -- the program is still too large. For debugging these kinds of
problems, it is often useful to strip everything that is not necessary
out. Set all of your coefficients to one (i.e., omit them from the code
altogether), remove the loop over frequencies, remove the postprocessing
steps other than graphical output, etc. I bet that you can reduce your
current 724 lines to 250 this way, and it will be much easier to see
what could possibly go wrong in your code then.
