Hello everyone,

I am trying to solve a simple thermal problem but finding the documentation helpfully detailed yet overwhelming. My problem is on heat conduction within a cubic domain with internal heat generation.

I have studied the transient heat transfer problem in step 26, in addition to the laplace problem solved on a 3D domain in step 4, as well as the problem in Step 7 where Neumann boundary conditions are applied. These have gotten me up and running.

However, I am stuck on how to apply a convective heat flux boundary condition of the form: q = h(T-T_ext) programmatically, whereby I must choose the external temperature (T_ext) and the heat transfer coefficient (h) to define the boundary condition. Is this possible to do in deal ii? If so, how might one go about it? I would appreciate any existing implementation of convective heat flux BCs that I can build up on.

Thank you everyone,

Morris

Update: Please disregard my last question. I found some guidance on this thread from 2013 concerning Robin BCs: https://groups.google.com/g/dealii/c/JSWctuiEVoc/m/8Im_ME_8f6wJ
