Hi,
I am trying to model a laser melting simulation, where a solid is being heated by a laser source (refereed as a Gaussian heat source). For that, I took a domain (Grey color in the attached image) set it as Air (to incorporate convection effects) and then I patched a domain (Blue region in the attached image) with solid properties. But the issue is, I am not able to set any boundary condition to the patched area.
Any suggestion / answers how can I do that.
Thanks in advance.
Hello, you have to write a UDF for laser heating and then implement it on the boundary as required. As far as I know, by default, you will not be able to implement the heating source in ANSYS. Anyway, you have not mentioned whether your heating source is moving or not as the melting is progressed.
Dear Jitender Kumar Chaurasia,
as Akter Hossain already mentioned, you will need a UDF for the heat source, which needs to be compiled and hooked and then taken as a BC under Boundary Conditions -> Type Wall -> Thermal -> Heat Flux -> udf_profile.
However, I have a remark on your numerical setup. You do not really need to have air in order to account for the convective cooling. You can simply define it by setting a Heat Transfer Coefficient under Boundary Conditions -> Type Wall -> Thermal -> Convection -> Heat Transfer Coefficient. So you will also not need to patch any material properties to the solid domain since this will be the only domain to consider. I hope this helps ;)!
Best regards,
Antoni Artinov
Also, I have this problem. if you could solve this, please help me.
