@grmnptr will help with the modification of some of the existing classes in LinearFV to make this PR work properly.
Thanks!

Yeah thanks for the early review! I'll address the comments, but at this point this is at a draft phase, will change a lot. Ramiro is testing it now on a simple channel case.

Please remember to add the testing that we previously talked about. These tests are:

• 1D problem with cp=a+bT and verification against analytical solution
• 2D problem with wall heating and verifying enthalpy balances (h_dot_out = h_dot_in + q''_wall * A_wall)
• Equivalent problem in 3D and test against the previous 2D problem
• Body with variable cp and rho cooling at a fixed heat rate and verify against the analytical solution

Thank you!
