Hi everybody,
I have the same question with this discussion: https://www.comsol.kr/…/pressure-wave-generation-due-to-the…
It's about laser-ultrasonics simulation, the first phenomenon is laser heating is now ok.
But to link between thermal stress and acoustic, I found this research: https://www.sciencedirect.com/…/artic…/pii/S0041624X14002327
They mentioned about " A prescribed displacement (in r and z directions) boundary condition was set in order to impose the thermal displacement, the output of the thermal stress module, as the input of the acoustic one."
However, I am not sure about this step.
So can anyone can suggest to me how to deal with this problem?
Thank you for your time.

Excuse me, I want to know whether laser heating occurs on the surface and then conducts heat in your model. In fact, I am looking for an example to solve my problem. I need to build a model that laser heating directly happens in the body of waveguides, but in most examples laser heating occurs on the surface and then conducts heat.

Sorry for my late repsone. I am trying to develop a model that is close to this research: https://www.comsol.com/paper/download/181573/cavuto_paper.pdf If you have the same question, we will talk more about it. Thank you.
