That's correct, you'd need source term *coefficients* (not actual source terms) for energy if the heat fluxes were giving convergence problems. Note that if heat fluxes were fairly stable and forces...

smagmon's assumption was correct. With 0.75, only 75% of the CHANGE in load is included PER STAGGER. So as you iterate within a timestep you get the full load. If you assume the load is constant...

This is a relaxation factor for the loads (force, displacement, heat flow or temperature) passed between ANSYS and CFX. The default means that 75% of the change in the load will be passed. A value...
