Answer:
The most significant difference between the RWIND 2 Basic vs. Pro options is the simulation type. The Basic edition applies a steady-flow simulation. The Pro edition contains everything that is available in the Basic edition, but also provides new options and features including the transient flow simulation using a more advanced turbulence model (Spalart-Allmaras DDES).
For a full list of features compared in both versions, please refer to the RWIND 2 online manual RWIND Basic and RWIND Pro section with the link below.
