TransAT Tutorial Manual 2.2. Flow over a group of Buildings

2.2 Flow over Buildings

2.2.1 Prerequisites
• TransAT

• TransATUI

• Paraview (or Tecplot)

2.2.2 Problem

Turbulent flow over several buildings is simulated.

The following tutorial utilises the Immersed Surface Technology (IST) capability of TransAT,
by which solid objects can be incorporated into the fluid flows. The CAD file of the buildings
must be imported into the TransATUI, and finally meshed appropriately, before the solution can
be executed.
This tutorial is beneficial to learn how to use the multiblock and IST capacities of TransAT.

2.2.3 Launching TransATUI
• Double-click the TransAT icon on the Desktop.

2.2.4 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 flow over buildings, 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 buildings 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.
