Thanks again for your advise.
I did some simple cases of my geometry...lets see if can come closer to the solution with them.

I've read the thread about plotting but gnuplot was working so I...

gnuplot p;N;N' or N;N;p'

Hi,

I've tried to plot the residuals and it works quite fine but I have problems understanding this part:
