I am trying to modelize the heat fluxes through a volume with one of his surface heated by concentrated solar light. The high temperature makes it necessary to take into account all three heat transfer media which pushed me to simulate in “conjugate heat transfer”.
To ensure the feasability of my project i started with a simple volume, a cube. I put it in a flow region to simulate the convection and radiation around it then added my boundaries, the first one being natural convection inside my flow region and the second one being my heat flux on one of the cube’s surface. Of course I now have the error “multiple boundary conditions…”. Is there anyway for me to have both natural convection and a heat source on one of the cube’s faces?
Thank you for your time,
