Qvol/Qbody depend on Node temperature in Heat Transfer Transient

Hi expert,

I am using OptiStruct to perform a transient heat transfer analysis.
I know that it is able to define a thermal load (Qvol/Qbdy) varying with time (time dependent).
But is it possible to create a thermal load which is depend on a specific node temperature?

Thank you!

    Time varying convection

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