Linear convection analytical solution code
Nettet6. mai 2024 · Once found, I suppose we have the solution for the whole problem. I guess I should maybe manage the two (f''(0) = a ; theta'(0) = b) but I don't know how to manage these two in parallel. Last think to mention, if I try to get the initial value of theta' (so theta'(0)) I don't get the right heat profile.
