Reply To: APDL Command to define material properties

[Jingyi Liu]

Thank you Erik.

I have already gone through this course, and I have defined enthalpy. I just need some assistance with changing materials in simulation using APDL because in Powder Bed Fusion (PBF), the powder bed and the molded solid are equivalent to two materials. In this course, it only involves the melting and solidification of the solid, not the powder melting and solidifying into a solid. However, in the simulation of PBF, I need to change the material from powder to solid. Because if the material is not changed, the powder data will still be used during the solidification stage when the temperature drops, which will cause calculation errors and seriously distort the results. Have you any experience with this or ideas?
