Hello, 

I'm perfoming a Thermal analysis with optistruct. The MAT4 card image let me use only a costant value of H (free convection heat transfer coefficient).

ow can I set H according to a coordinate?

Thanks

    Time varying convection (Available for Version 2018.0 or higher)

    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.
