TransAT Tutorial Manual 1.1. Turbulent Channel Flow

• Fluid: Air

• Reynolds number = 24000

1.1.4 Launching TransATUI

• To launch TransATUI, double-click the TransAT icon on the Desktop.

1.1.5 Opening TransAT window

The first step in creating a new TransAT project is naming said project and giving it a location.

• Click to create a new project

• In the next window, navigate to the folder where the project will be saved

• To create a new project folder, click in the top right corner of the window

• Enter a project folder name, say channel turbulent, then click to create the folder

• Click to select the folder and close the browser

• Set Project Name to a more explicit name such as channel turbulent then click

After clicking , the Mesh & BCs tab will be opened.

The Geo, Mesh & BCs, Input and Execute tabs at the top of the TransATUI window can
now be selected to open the modules to set up a simulation with TransAT.

Geo is a module that can be used to create simple geometries for TransAT. The grid properties
are defined in Mesh & BCs tab whilst the physical and numerical parameters of the simulation
are defined in the Input tab. When the simulation is ready, the simulation will be started from
the Execute tab.

Some general operations such as saving and loading projects or exiting TransAT can be done
by clicking Files then selecting the corresponding option.

1.1.6 Mesh & BCs Tab

The computational domain is defined and the mesh is created in the Mesh & BCs tab.
• Select the Mesh & BCs tab at the top of TransATUI if that is not already the case.
