Hi all,

Im trying to simulate a gas turbine combustor for which I know inlet conditions (massflow, pressure, temperature) and I want to evaluate efficiency of the combustor based on the outlet conditions.

I have experienced that OF blows up whenever I specify at the inlet (fixedValue BC) either:

a) temperature pressure and velocity (T p U - fixedValue)
b) pressure and massflow (p phi - fixedValue)
c) pressure and velocity (p U - fixedValue)

The other quantities are set to zeroGradient (note for velocity also used pressureInletVelocity). FYI, im using reactingFoam which uses PISO solver for momentum equations.

This is a simulation for my master thesis, so I really need your precious help. Any suggestions?
Thx
