Click on the Grid menu in the main toolbar, a number of options are shown in Figure 1. The function of options are described in the table below.
Figure 1 Grid menu options.
| Options | Description |
|---|---|
| Refine Grid | This option allows the user to increases the resolution of the grid. It operates by multiplying the existing number of cells in the current grid with I and J directions independently. |
| Coarsen Grid | This option operates in an opposite way to that for Refine Grid. It decreases resolution of the grid. |
| Orthogonalize Grid | This option is used to reduce the orthogonal deviation of a grid. |
| Merge Two Grids | Often the model domain is too complex to create a single grid that accurately represents the area. Therefore, the user may have to create several grids and connect them using the Merge Two Grid tool. |
| Delete Selected Grid Block | When a grid block is selected, using this option will delete grid nodes inside the the block. |
