Reply To: APDL Command to define material properties

Thank you, Erik, but I have already addressed this in the Engineering Data. What I mean is that when the temperature exceeds the melting point, ANSYS should switch to calculating with the properties of solid material.In the pictures you could see that there’s a significant difference in values between powder and solid when the temperature is below the melting point.

For instance, the material I’m using is copper, which has a melting point of 1365K. Below 1365K, ANSYS should use the properties of copper powder for calculations, while above 1365K, it should switch to the properties of solid copper. This switch is crucial because, after melting, copper transforms from a liquid to a solid, not back to a powder, and the cooling process should be calculated using the data for the solid. The theory might be complex to explain and understand. However, I need to insert an APDL command to achieve this. 

My question is, how do I define this in APDL? I believe it might involve an if-else statement or something similar. My knowledge of APDL commands is quite basic, so I am struggling to figure out how to implement this in APDL.

Best regards
