Hallo, In simufact laser welding simulation, the heat source deviates from defined path (may due to deflection of plate). Results in the sudden rise of temperature along the laser path. Used 0.3 mm mesh and 0.005s time step. Anyone help me to solve.

deflection of heat source
In the above you can see the formation of heat source in sideways
laser path
In this above picture, you can see the suudden jump of temperature in the path .
