Hello all, This has been a problem that I have been trying to solve for a while but could not figure out what is the issue. IBVP: Cubic domain of 1mm x 1mm x 1mm Initial Temperature: 300K Dirichlet BCs: Temperature: 320K at boundary X=0, Y=0, Z =0 Neumann BCs: Heat flux of -1000 mW/mm^2 at…

Looks like your boundary conditions are not consistent with your initial conditions, so you’re effectively seeing Gibb’s phenomenon .

Hi Nate, Could you tell me more about how I could correct this? If boundary conditions, what should it satisfy? Thank you!
