- Select the grid layer in the Layer Control by LMC
- From Grid menu, select Orthogonalize Grid or the user can click on the Orthogonalize grid button from the main toolbar as shown in Figure 4. As a result, the entire grid will be orthogonalized immediately.
Figure 5 shows orthogonality change of the grid after applying Orthogonalize Grid. If the user keeps using the option, an informing message will appear when the orthogonality reaches a limitation as shown in Figure 6, click OK button to exit the form.

Figure 3 Orthogonal deviation of a grid.
If a global operation is selected the entire grid will be orthogonalized immediately. If a local operation is selected, the user must define two grid nodes and the area of the grid limited by the two points will be orthogonalized. Orthogonalize 1D feature is similar to the Orthogonalize Local option but is only applicable for a 1D grid region. In case the feature is applied for an improper grid region, a warning message will appear.
The change in grid orthogonality before and after applying Orthogonalize Global are shown in Figure 2 and Figure 3. It may be seen in the first image that the average orthogonality is 20.3. In the second image, after CVLGrid has automatically reduced the orthogonalization, it is only 2.6.
The change in grid orthogonality before and after applying Orthogonalize Local are shown in Figure 4 and Figure 5.
The change in grid orthogonality before and after applying Orthogonalize 1D are shown in Figure 6 and Figure 7.

Othogonalize grid block
- Select the grid layer in the Layer Control by LMC
- From main toolbar, select the Select object button then select a grid node, hold Shift key and select the second grid node. The grid block will be highlighted as shown Figure 7.
- Next, from Grid menu, select Orthogonalize Grid or the user can click on the Orthogonalize grid button from the main toolbar. In the other hand, the user also can select Orthogonalize Grid Block from RMC's options as shown in Figure 8. As a result, the grid block will be orthogonalized immediately. Figure 9 shows orthogonality change of the grid after applying Orthogonalize Grid for a grid block.
