Grid Generation

The following steps introduce how to create a grid:

1. From the Splines menu, select Draw a New Spline or click on the Add a new spline button from the main menu.
2. LMC to start drawing spline, RMC to end drawing spline. Two first splines need to be done.
3. The last two splines are drawn along the sides of the domain and must intersect the previous two splines (Figure 1)
4. RMC on the Splines layer in the Layer Control, then select Create Grid... option or click on the Create Grid from Splines button from the main menu, as shown in Figure 2
5. Create Grid from Splines form will pop up as shown in Figure 3. From this form, the number of grid cells needs to be defined by entering a number of cell in I and J directions (default values are 4). The values input for Growth Factor will define the spacing distance for nodes of the grid, with default values (zero), nodes are distributed evenly in I and J directions. Figure 4 show examples for grid generated.
