when I enable compressibility effects and vicious heating after some initial running the omega jumps to a certain value and keeps that constant value without changing. I presume that is becoz of:
absolute pressure limited to 1.000000e+00 in 2 cells on zone 3
394 1.0367e-03 4.8971e-04 3.8405e-04 9.2596e-04 3.1387e-05 8.5587e-04 7.9988e-01 34:31:16 49903
temperature limited to 1.000000e+00 in 6 cells on zone 3 in domain 1

the limiting stuff, but why does it happen?
I have a nozzle of 1mm which is modelled as mass-flow inlet where 0.16g/s expand/go through.
Atm I'm using Soave-Redlich-Kwong real gas

edit: ATM it looks like specifically the "compressibility effects" seem to induce that weird behaviour. Is there anyone which has had experience in handling such flows, coz I presume for these kinds of flows it should be included...

edit2: Also is it reasonable or advisable (and if so where is the option?) to change the limit temperature and pressure of 1?
