Time Dependent PCONV definition for heat transfer analysis in HyperMesh

Damla

Hi, I'm doing a time-dependent heat transfer analysis in HyperMesh 2024.1. I need to define time-dependent convection. Instead of using CONVG, I'm defining CONVECTION. I entered the ambient temperatures using time-dependent SPC, SPCD, TABLED1 and TLOAD1. However, I'm not sure how to define the PCONV for a transient heat transfer coefficient (htc). Could you please help me with this?

Thanks in advance.

Hello,

Convection coefficients can be time dependent when a control node (CNTRLND) is specified on CONV card. The control node must be constrained by SPCD, which is made time dependent by TLOAD1/TLOAD2. Convection coefficient is multiplied by the value from SPCD of control node.
