Hello everyone. I need to simulate the heating from laser beam almost to the center of my structure. I’m trying to use formulas to simulate a circular surface heat flux of 20 mW/m^2 at the center of my structure. Using bigger values of surface heat flux I’m able to get the temperature gradient on m…

hi @mrosalia , Look like the same question you were asked a few days back. [image] I'm not able to start simulation Using SimScale Hello @rszoeke , thanks a lot for your reply. I think I got what you mean, I think I just applied the boundary conditions for input surface hea…

@rszoeke solved my problems adjusting the boundary conditions. He applied a a value of 20 W/m^2 of surface heat flux and the simulation worked properly. When I tried to drop the value of surface heat flux to 20 mW /m^2 I’m able as well to launch the simulation. When I check the post-process simul…

@mrosalia I think you should have to apply the realistic surface heat flux value to visualize the temprature gradient clearly. In your case the outer convective heat flux is around 50 W/(K·m²) means your outer surfaces are capable of loosing heat more rapidly than you are providing by input surface …

Thanks for the advice @HamzaBaig . I’ll try to do that. Best regards

I was having the same problem. I used solidworks previously for some thermal simulations and I could simply put 50 W of power to a specific surface. Here it seems like it is different and would like to hear others’ opinion. My interpretation was that when we enter 50 (w/m^2) heat flux the power in…

hi @mrosalia,
Look like the same question you were asked a few days back.

and @rszoeke sir has solved your problem already( Run 1 in your case)
than what your problem right now?
and how this problem was different than the previous one?
can you elaborate?

can you share the amount of that surface heat flux?

happy to help you.

best,
Rohit.
