hi there

I am trying to simulate train-tunnel interactions in 2D. I attached the two domains i am using and the boundary conditions imposed. i solved compressible navier stokes equation.used every turbulent model that's there in fluent. The problem is that i couldn't capture the pressure variations as were in papers which i monitored at various points on the tunnel. i couldn't figure out what the problem is.

Used sliding mesh for train domain and tunnel cell zone is kept stationary.
