Description
Transient solver for buoyant, turbulent flow of compressible fluids for
ventilation and heat-transfer.
Transient solver for buoyant, turbulent flow of compressible fluids
for ventilation and heat-transfer, with optional mesh motion
and mesh topology changes.
Turbulence is modelled using a run-time selectable compressible RAS or
LES model.
