Reply To: Reference Pressure Location?

[Karthik Remella]

Hello Reference Pressure is important for incompressible flow simulations without any pressure boundaries. This helps fix the pressure in the computational domain to a known value. If I understand your simulation, the location of the reference pressure should not affect your results. If you wish to read more about the reference pressure location, please have a look at the following link from the Fluent User's guide.
