I am trying to resolve the steady compressible flow around an airfoil. I need a B.C similar to Pressure farfield BC in FLUENT.
does this BC exist in OpenFoam ?


The definition of this BC in the fluent manual is:

Pressure far-field conditions are used to model a free-stream condition at infinity, with free-stream Mach number and static conditions being specified. The pressure far-field boundary condition is often called a characteristic boundary condition, since it uses characteristic information (Riemann invariants) to determine the flow variables at the boundaries.

for more information about the Calculation Procedure at Pressure Far-Field Boundaries please see the below link

this B.C is used for compressible flow.
