Default Only Radiation
Posts: n/a

I am doing a transient simulation with S2S radiation model and i need to know if there is a way to kill the effects of natural convection.(i.e. consider only radiation.)

I have tried changing my fluid zones to solid (my fluid was air). My idea is to create a sort of vacuum insted of air and to study only the effects of radiation.

Thank you, Alt

Solve only the energy equation. Or set gravity to zero. Or change the thermal capacity of the fluid to 1E-30.

Or define->bc->fluid, check "fixed values" and set x,y,z velocities to constant=0 (kind of brutal).
