Reply To: Mechanical APDL-Element Birth and death

[Neil]

Sorry,

I am currently using ANSYS APDL to simulate a model of a four-layer laminated board. However, I have encountered some challenges regarding the temperature heating-up to 230 degrees Celsius in the third step and the temperature cooling-down to 25 degrees Celsius in the fifth step. These temperature values do not align with the experimental data, and I am unsure if there might be an error in my settings.

I have included the coding I used for these steps below for your reference. I would greatly appreciate your assistance in identifying any potential errors or suggesting any necessary adjustments.
