This is actually a request, I don't know if these are the correct forums for me to post these kinds of things, but yeah. Alright. I intended to study and learn numerical methods with PDEs on my own. And sadly the only thing I can comprehend is the Liebmann method. And I got so little time our professor didn't have the luxury of time to discuss numerical methods for PDEs (but I fear that I may encounter these problems soon, and I don't want to be a sitting duck when that time comes). So yeah, can I ask for at least a basic/step by step pseudo-algorithm for numerical techniques for PDEs? Because I read Kreyszig's and O'Neil's book and yeah, the only thing I can comprehend is the Liebmann method.
