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
