Solving PDE time dependent
Hi there!
I'm looking for a way to solve parabolic time dependent PDE (sth like Ut=Uxx). Actually, I'm trying to write down my own solver since I need to perform some peculiar calculation, so what I'm asking is: what kind of loop/iterative method should I use? Since I'm quite new to CDF, I don't know all the possibilities and the different type of loops. Thanks in advance! 
hi firend
openFOAM solves pde equation for learning look into basic solver! for example a syntax like this in OpenFOAM can solve ur problem Code:

Thank you!
I am ashamed of my question. Just did not think enough. It was obvious. I had already written that line of code, I just thought I needed something more "complicated" .'' And can you give me some info about solving eigenvalue problems (like Uxx=lambda *U? I need the solver to find both lambda and U. I thought something like making a loop on lambda and see which solutions are nonzero, but I don't think it would work and I guess there are less expensive ways. Thx
