I am attempting to use the Laser DTRM feature with the icoReactingMultiphaseInterFoam solver. I am trying to model a moving laser. When the laser is stationary, heat is transferred as expected, but when it moves (as below), the barely any heat is transferred. Am I missing something, or is there a better radiation model to use?
