TransAT Tutorial Manual 4.1. Dam Break

• Enter a project folder name, say dam break, 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 dam break 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.

4.1.4 Mesh & BCs Tab

In the Mesh & BCs tab, the domain along with the mesh are defined.

• If that is not already the case, select Mesh & BCs at the top of the TransATUI window

4.1.4.1 Domain & Grid tab
• Select the Domain & Grid tab

• In the Domain section, set the following values for the boundaries (see Figure 4.1)
X min : 0.0
X max: 1.795
Y min : 0.0
Y max: 0.8975
Z min : 0.0
Z max: 0.2

The number of cells in the domain and the refinement zones is also defined the Domain &
Grid tab. In this case, a uniform mesh will be created for the simulation.

• Change the values of the properties of the grid in the different directions so that they
correspond to the following values (see Figure 4.1)

Nx: 80 , Cell Ratio : 1.0 , Maximal Ratio : 1
Ny: 40 , Cell Ratio : 1.0 , Maximal Ratio : 1
Nz : 2 , Cell Ratio : 1.0 , Maximal Ratio : 1
