The Heat Transfer with Surface-to-Surface Radiation multiphysics coupling forces a strong coupling between temperature and radiosity variables solved by a Heat Transfer interface and a Surface-to-Surface Radiation interface, respectively. The default solver suggestion ensures that the temperature and the radiosity dependent variables are solved together, either by a fully coupled nonlinear solver, or by placing them in a same segregated group when other segregated groups are generated by some other physics interfaces.
The Local Thermal Nonequilibrium multiphysics coupling forces a strong coupling between both the solid and the fluid temperature variables involved in the porous medium model. The default solver suggestion ensures these two temperature dependent variables are solved together, either by a fully coupled nonlinear solver, or by placing them in a same segregated group when other segregated groups are generated by some other physics interfaces.
