I'd like to simulate thermal deformation of a thin glass due to a laser heating with extra pressure.

Hello,

I just attached the concept file that shows what I want to simulate. I'd like to estimate how a thin glass is deformed when it is heated upto the softening temperature by a laser beam under extra pressure.

Is there a good example or tutorial that I could try?

Thank you.

Hello Hoon,

You can combine elements of the following two models:

https://www.comsol.com/model/laser-heating-of-a-silicon-wafer-13835 demonstrates the heating of a substrate by a gaussian laser beam

https://www.comsol.com/model/heating-circuit-465 demonstrates the thermal deformations of a glass substrate when it is heated

Best,

Jeff

Hello Jeff,

I'm going to look at that. Thank you so much.

Bests, Hoon.

Hello Jeff,

I have another question.

The tutorial you suggested me seemed the glass is treated a solid. For my concept, however, the temperature of the glass is going to be higher than softening temperature and I think it should be treated as like solid from the initial temperature to fluid in final state.

Is there a example about a glass blowing? I can find several papers about the simulations of glass forming and blowing with comsol multiphysics, but it is very hard to find an example which teaches the beginners.

Thanks, Hoon.

Hi Hoon,

Ohh hand, I am not aware of a tutorial in the area of glass blowing, but, you know, there are so many resources out there that I don't know them all. I would suggest contacting the authors of the papers you've found; researchers are usually happy to discuss their methods.

Best,

Jeff
