Hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

I found this forum by chance. Was wondering if anyone could help out with my problem. I am very new to this COMSOL and I am required to tackle a problem.

I am required to simulate laser drilling onto a material using comsol to obtain the heat transfer pattern. I have chosen silicon in the drop-down box

I used the New>FEM>Heat Transfer>Conduction>Transient Analysis.

I then created a rectangle with 3 sides thermally insulated and the top is having heat flux.

Under Boundary settings, I need to enter the equation in the Q field as the heat source

The equation is like this: (10^7) x exponential (-10^3 x X^2) for a time of 2 seconds.

I keep having syntax errors. How do I put in the equation properly?

Thanks.
