Hello Everybody,
I am a beginner in CFD
i am trying to simulate the LSB and other coefficients for Low Re 70 000 , using SST transition model , i need help in proper settings ,

my current settings are :
convergence criteria: 1e-4
meshed rotated at -5 for 5 deg AOA
Velocity inlet : at X=1.02 , y=0

Intermittency =0 ,
Turbulence intensity : 0.12 ,
Turbulence viscosity ratio : 2

pressure outlet:
Turbulence intensity : 0.12 ,
Turbulence viscosity ratio : 2
Intermittency =0

my domain is extended from -15 to 25 times the chord
i am using SIMPLE scheme with default settings for relaxation factors

1- how can i capture the LSB ?
2- What do you think about my settings? is it good?
3- what should be the operating conditions at inlet and outlet with rotation of the mesh ?

thanks in advance

Haseeb
