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 : 5000
Autorelaxation : 0.6

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 Residue is
checked. The check box should be colored in orange

• Set the Convergence Tolerance value as follows
Convergence Tolerance : 1.0 e−6
