Hi,
I'm trying to solve 2D heat flow problems between two different media. I am starting with simple cases but eventually would like to model more sophisticated problems. I can solve the problem in 1D but when I try to solve the problem in 2D, I get an error message that refers to the boundary conditions specified at the interface between the two media. Here is both the 1D code and 2D code.
If someone could point me in the right direction, I would appreciate it.
