Hello,
I wrote a UDF for Mach No. in Pressure far-field Boundary Condition based on 7th power law to avoid a shock at inlet during simulation.
I use the following boundary condition:
Inlet: Pressure far-field with UDF for Mach No.
Wall top and bottom: wall
Outlet: Pressure outlet
But even with UDF, I am getting a shock at the inlet. Please find the UDF file attached.
I checked the boundary layer at the inlet but it is not developing as desired.
