ANSYS governing equation

    • Walaa Elhamamy

      Hello everyone,

      I am using ANSYS fluent to simulate a flood case running on stairs, my flow is transient flow and I am applying the VOF method, and applying k- Ɛ for the viscous model.

      I am confused about the governing equation that is applied here, is it Navier-Stokes equations solved by Direct Numerical Simulation(DNS) ? or Reynolds Average Navier-Stokes (RANS) equations?

      I suspect you may want to start with some of the AIS materials in Learning (book icon left, upper).
