Physics

Flow conditions and fluid properties

      1. Flow conditions: inviscid, viscous, laminar, or

                                      turbulent, etc.

      2. Fluid properties: density, viscosity, and

          thermal conductivity, etc.   

 3. Flow conditions and properties usually presented in dimensional form in industrial commercial CFD software, whereas in non-dimensional variables for research codes.

Selection of models: different models usually fixed by codes, options for user to choose

Initial and Boundary Conditions: not fixed by codes, user needs specify them for different applications.
