So I’ve been trying to follow along with the laser hardening project by ahmedhussain18 and I guess I don’t quite fully understand the heat flux equation he uses. The problem I run into is that I want to do a simulation using a small 56um diameter laser spot size (typical for fiber lasers used in cutting and welding) but it seams that when I get to that scale, the equation tends to 0 for some reason. This could be an issue with how I input the equation.:
Should I be using the measured spot size as opposed to the theoretical spot size of the laser?
Thanks for any help!
