How to do multi track modeling?

Please login with a confirmed email address before reporting spam

Hello, I am doing laser based powder bed fusion modeling in COMSOL. I know how to do single track laser modeling, but I am facing some issues with multi track laser. I have actually been able to create multi track. But the problem is, all the laser beams are working simultaneously at the same time. If you see in the comsol file I have attached, I have input 0 to 20 seconds for the 1st track (analytic 2), 21 to 40 seconds for the 2nd track (Analytic 3) and 41 to 60 seconds for the 3rd track (Analytic 4). In study-time dependent, I have selected the total run time to be 60 seconds. But still, all the beams are running at the same time. Can you please tell me what should I do so that the 2nd track starts only after 1st track is finished and the 3rd track starts after the 2nd track is finished?

Thank you, Faiyaz

I not really know what kind of effect you want to bring out. Acourrding the model you up load i think you can disble the Heat flux in Physics and variables selection while Modify modle configration for sdudy is selected.
