               Simulation Parameters
                  The numerical parameters of the simulation are set in the simulation parameters tab.
                   • Click Simulation Parameters on the left-hand side of TransATUI

                   • Set the following parameters to solve for a steady flow
                     Simulation Type : Steady
                     Number of I t e r a t i o n s : 1000
                     Autorelaxation : 0.9


               Equations Section
                  In this tab the convergence threshold is defined, as well as the convection scheme and other
               parameters of the solvers used by TransAT. Modify the convergence thresholds as follows:

                   • In the Equation tree highlight All Quantities and make sure that Normalised is checked. The
                     check box should be colored in orange
