Hi. I'm solving a PDE that is partially elliptic. So I need to solve the equation iteratively. My problem is at the end of the code. I'm doing interactions manually in order to evaluate the code. At the second interaction, I don't know why NDSolve...
Hi, I've been having a problem with a function definition. Here is all my code. vm = 5; r0 = 127.25; di = r0*2; de = 273; v = 0.000000464; ?f = 958; ?t = 7854; pr = 2.88; kf = 0.656; kt = 58; ...
