hi
my domain is a quarter of the original geometry of supersonic wind tunnel.wind tunnel mach number is 1.8 . in my domain Using tow symmetry boundary conditions and tow wall boundary condition and a boundary condition input and an output boundary condition my simulation cfx Boundary conditions is:
ANALYSIS TYPE:
Option = Steady State
TURBULENCE MODEL:
Option = k epsilon
BOUNDARY: inlet
FLOW REGIME:
Option = Subsonic
END
HEAT TRANSFER:
Option = Static Temperature
Static Temperature = 300 [K]
END
MASS AND MOMENTUM:
Option = Total Pressure
Relative Pressure = 1.8 [bar]
TURBULENCE:
Option = Medium Intensity and Eddy Viscosity Ratio
END
BOUNDARY: outlet
Boundary Type = OPENING
Location = outlet
FLOW REGIME:
Option = Subsonic
END
HEAT TRANSFER:
Opening Temperature = 300 [K]
Option = Opening Temperature
END
MASS AND MOMENTUM:
Option = Opening Pressure and Direction
Relative Pressure = 84000 [Pa]
END
TURBULENCE:
Option = Medium Intensity and Eddy Viscosity Ratio
END


wall
HEAT TRANSFER:
Option = Adiabatic
END
MASS AND MOMENTUM:
Option = No Slip Wall
END
WALL ROUGHNESS:
Option = Smooth Wall
END

After 1600 itration cfx solver stop solution .
The error is in the attached image:
Please Help me, please
Thanks for all

Looks like an FAQ:

and

try to change the turbulence model to sst.
If this doesnt work try to change opening to an outlet with static pressure.

We already have. If you do not respond to the suggestions already here then we are not going to bother suggesting anything else.
