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

Simulation Type and Control Parameters

• Click Simulation Parameters on the left-hand side of the TransATUI

• Select Steady in the drop-down list of the Simulation Type section

• Set the Number of Iterations field to 2000

Initial Conditions
In this tab simple initial conditions are set.

• Select the Initial Conditions tab on the left-hand side of the TransAT user interface

• Click U-Velocity in the quantity tree

• Set Method to Constant and Value to 0.01

• Proceed as above to set the initial state of the remaining quantities as follows
V−Velocity
Method : Automatic
Temperature
Method : Constant
Value : 300

Pressure
Method : Automatic

Output Management
In this tab the parameters of the simulation outputs are set. For this example, only the
visualization output will be defined.

• Click Output Management on the left-hand side of the TransATUI

• Set the Output File Format and Frequency of output files from Iteration / timestep
number as follows
Output F i l e Format : Paraview
Frequency of output f i l e s : 100
