I would like to solve a multiphysics problem involving navier stokes, heat equation and magnetic field (actually a TIG welding problem ). I have some graphics involving the viscosity, density of the Argon gas changing with the temperature. How can I implement these graphic values into COMSOL . Should I change these graphic values into third or fourth degree equations or is there a way to implement them directly. I use COMSOL 3.5a
