               7.1.7    Input Tab

               To set up the simulation parameters

                   • Click Input at the top of the TransATUI


               Physical Models
                  In this tab, the models that will be used during the simulation will be defined.

                   • Select the following equations in the Basic Equations section
                     Basic Equations :
                        Pressure       : ON
                        U v e l o c i t y  : ON
                        V v e l o c i t y  : ON
                        W v e l o c i t y  : OFF
                        Temperature    : OFF
                        Concentration : OFF

                   • In the Models and Properties section activate Turbulence Modelling and set the model
                     RANS (drop-down list)

                   • Activate Gravity and click    to the right.


                   • Set the following parameters in the Gravity window them click   to save the settings
                       x : 0.0
                       y : −9.81
                       z : 0.0
                       CHECK Hydrostatic


                   • In the Mulitphase section activate Phase Average and set the model (drop-down list) to
                     Algebraic Slip Model

                   • Click   , set the following parameters then click
                       Number of phases : 3
                       Keep the default values .
