Hey all, a quick question about AM simulation in Abaqus. Hopefully this is something simple I'm just not quite grasping.
As you know, in thermo-mechanical simulation, it is a 2-step, sequential process. The NT output of the heat transfer simulation becomes the input to the mechanical.
I pulled the TEMP results from the .odb of both the heat transfer and the mech simulation, expecting the temperature evolutions to be the same. However, the mechanical (ST) results are generally ~500 degrees cooler at each point.
As far as setup, this is for a five layer part, not including the build plate. Since the mechanical simulation is a mechanical one, I'm unsure how it could be changing the temperature history. This occurs no matter the model's layer total.
I feel I should be getting the exact same temperature curve for both. I appreciate any clarification you can provide!
