TransAT Tutorial Manual 2.3. Flow in an obstructed pipe

2.3.4 Launch TransATUI

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

2.3.5 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 obstructed pipe flow, 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 obstructed pipe flow 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.

2.3.6 Geo Tab
A pipe geometry and a disk (cylinder) are needed for the simulation.

• Click Geo at the top of the TransATUI.

• Click Create Shape tab within the left panel

• In the shape selection drop-down list next to the button, choose Pipe.

• In the text field below the drop-down list, set the name of the object to be created as Pipe
