Fluid heat transfer, temperature field simulation of laser cladding

Please login with a confirmed email address before reporting spam

Hello everyone, I am a new graduate student of COMSOL. Recently, when the temperature of laser cladding was simulated, it was found that the maximum temperature fluctuated too much in different time steps. Up to 200-300K. On the axis of cladding trajectory, the maximum temperature peaks differ too much.Excuse me, is this normal? Can the temperature field simulation data be used normally? Is there a theoretical explanation? I hope you academic leaders are generous with your advice. Look forward to your reply, thank you.
