No.

Sripada Raja

Thomas Frank - Can you elaborate more?

Reynolds number is not a required input parameter for an ANSYS Fluent simulation and ANSYS Fluent is not predicting a Reynolds number by itself. Consequently for any CFD simulation the terms of the Navier-Stokes equation (including convective terms) are discretized and solved irrespective of the governing Reynolds number.

Regards,

Dr. Th. Frank.

Thank You.
