TransAT Tutorial Manual 6.1. Wall Boiling

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

• Enter a project folder name, say wallboiling, 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 wallboiling 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.

6.1.5 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

Domain & Grid

• Select the Domain & Grid tab

• Set the following values for the boundaries in the fields of the Domain section
X min : 0.0
X max: 5.0
Y min : 0.0
Y max: 0.0096
Z min : 0.0
Z max: 0.001

• Set the values of the grid parameters as follows to define the cell density in the domain
Nx: 501 , Cell Ratio : 1.0 , Maximal Ratio : 1
Ny: 8 , Cell Ratio : 1.0 , Maximal Ratio : 1
Nz : 2 , Cell Ratio : 1.0 , Maximal Ratio : 1

Blocks
In TransAT, the domain can be decomposed into several blocks so that the simulation can run
on several processors. Indeed, each block is allocated to one processor (but a processor can handle
several blocks). This case does not require such action and will be left as a single block.
