Wall-Material heat lost
 

Hi Everyone

I’m a beginner (brand new) with CF Design, I’m trying to simulate heat lost (heat gain) from the surroundings, room air volume (in gray) to the small enclosure (part in black).
I’ve started with boundary conditions of 0 psi and 80F for the top surface of the surrounding volume (room) and -5F for the air volume inside the black part

The simulation is not working, I can not see the temperature gradient in the wall (black part) and the ‘heat lost’ cause by the surrounding

All this manipulation ans simulation is to get use with the software afterward I want to implement TE’s module for cooling base on the capacities needed



Thank you
