Default wall heat flux or boundary source of energy???
Posts: n/a

i should impose an heat flux for a wall boundary conditions.

What is the differences between the choice of heat flux (under boundary details panel->heat transfer->heat flux) and the choice of a energy source (under source panel->source->Flux)?

Thank you.

Dear Albi,

A boundary source is just adding a fixed amount of energy to the equation at that boundary.

However, a heat flux specified condition satisfy heat flow continuity. That is,

Heat Flux = heat conduction + radiation transfer + other physics

Hope it helps,
