7.2.7 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 tab at the top of the TransATUI window

Domain & Grid

• Click the Domain & Grid tab and set the following values for the domain boundaries in
the Domain section.
X min [m] : −0.214
X max [m] : 2.0
Y min [m] : −0.001
Y max [m] : 0.001
Z min [m] : −0.06
Z max [m] : 0.06

• Enter the following grid parameters given below to define the cell density and aspect ratios

Nx: 125 , Cell Ratio : 1.10 , Maximal Ratio : 6
Ny: 2 , Cell Ratio : 1.10 , Maximal Ratio : 6
Nz : 23 , Cell Ratio : 1.10 , Maximal Ratio : 6

To refine the mesh do the following:

• Check Customized Refinement
• Highlight X-axis in the Refinement list

• Click

• Set the P1(X) field to -0.02m

• Click

• Proceed as in the last three steps to create two extra refinement zones. One for which
P1(X) is set to -0.01m and the other for which P1(X) is set to 0.0m
