Hello everyone,

I am modeling a steady-state thermal analysis where I am required to apply the heat flux and convection at the same boundary. When I do that one of them doesn't have any effect.

How can I do that with ANSYS workbench or with an APDL command?

Thanks.

I just tried it and it was possible.  It wouldn't be possible to apply both heat flux and convection to the face of the underlying elements, but Mechanical applies them both with surface effect elements making it possible.  I made a cube and applied a heat flux of 1000 W/m^2 to the top face and a convection on the same face with a film coefficient of 100 and an ambient temperature of 22 degC.  The temperature solution of 32 degC reflects both boundary conditions.

Hey dlooman,

Thank you for trying out.

I'm having trouble creating the surface effect elements and applying heat flux and convection.

Can you share the code you used with me?

Thank you again.
