hello, I am trying to simulate an hybrid laser welding model using COMSOl.. I need to use a 2D Gaussian heat source but I don't know how to define it or the expression to use.. could you help me?
thanks

Hi
try a search on the forum, it has been discussed a few times, and there are several examples out here

Dear User,

Using comsoI,I am trying to model laser welding of dissimilar materials while the work-piece is moving with constant speed beneath the laser nozzle.Unfortunately,it seems,I have roughly the same problem you had to define the heat source.(In my case I am looking to define a volumetric Gaussian heat source as I think the heat source should be w/m^3.

Now i just was wondering if you could kindly let me know how did you define the heat source in your case or if you have any idea.

Thanks for your taking time to read my email,

Kindly Regards
Reza
