Thank you for the responses.
@jousefm, I have been using at least two of those examples as guides in my efforts. With their help, I at least have meshing down and good understanding of the Numericals and Simulation Control.
@1318980, That is what I have been trying to do in the meantime. My only concern with splitting the model in half is the inaccuracy of the mixing at the back side of the solid heat source, particularly in the case of turbulent flow modeling. Although, this shouldn't greatly affect my results focused in the heat transfer. I do believe the Symmetry boundary condition would be helpful for such a split down the center of the geometry, but am not sure if this boundary condition is helpful for 3D geometry. Also, I'm having difficulty figuring out how to apply both the symmetry and external wall heat flux conditions to the cross-section of the solid heat source after being split. Is the symmetry boundary condition only for symmetry in fluid properties at each reflected point across the plane?
@AnnaFless, That is outstanding news! I look forward to this release.
