Hi Freddie, Thank you for your advice.
I set the initial velocity distribution using hyperbolic tangent function, and could run the case. Current issues are shock wave generation from bottom of inlet as shown in the attached figure and termination of simulation job with an error message "RuntimeError: Minimum sized time step rejected". I'm trying to solve the issue.
