Click After building a grid, it is necessary to modify and improve it. Clicking on the Grid menu in the main toolbar , displays a number of options are for this purpose, as shown in Figure 11143537899. The function of options are each option is described in the table below.

Figure 1. Grid menu options.
| Options | Description |
|---|---|
| Refine Grid | This option allows the user to increase 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 the 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 block. |
| Modify Indexing | This feature allows to change grid indices, including transpose I-J, flip I or J, and rotate I→J and J→I (1143537899). Transpose I - J Indices Flip I Indices Flip J Indices Rotate Indices Clockwise Rotate Indices Counter-Clockwise |
| Show Grid Properties | This feature allows showing grid's properties as shown in 1143537899. None Orthogonal Deviation Cell Area Cell Aspect Ratio Cell DX Cell DY |
| Show Grid Labels | This feature allows showing grid's labels as shown in 1143537899. None Nodal I,J Indices Cell I,J Indices Cell L Indices |
