TransAT Tutorial Manual 1.1. Turbulent Channel Flow

Simulation Parameters Tab
This tab is used to define the numerical properties of the simulation.

Simulation Type and Control Parameters
The simulation will be run till the flow reaches steady state.
• Click Simulation Parameters on the left-hand side of the TransATUI

• Use the following parameters to run a steady simulation solved with an implicit method.

Simulation Type : Steady
Number of I t e r a t i o n s : 500

Equations
In this section the convergence threshold is defined as well as the convection scheme and the
solvers used by TransAT. These parameters can be set for each equation individually.

• In the equation tree, click All Quantities

• Modify the Convergence Tolerance field besides the equation tree as follows
Convergence Tolerance : 1.0 e−5
