Line Smooth
The Line Smooth tool is used to smooth the grid domain and redistribute the distance between grid nodes. That will improve the accuracy of the model.
- Select a grid layer in the Layer Control
- RMC on a node, hold the Shift key then LMC on the second node (these two nodes must be in the same gridline), and the segment will be highlighted. And then RMC to display options, select Line Smooth option as shown in Figure 1. As a result, grid nodes are distributed along with the selected segment as shown in Figure 2. Note that after applying this option, the grid should be orthogonalized again.

Line Attraction
The Line Attraction tool is used to shift grid nodes forward to the selected gridline. The nodes in the defined area have a trend of translational motion to one direction (the selected gridline segment plays the role of is a destination).
- Select the grid layer in the Layer Control by LMC on that grid layer
- Set the mouse in the Selection model, hold the Shift then LMC on two edge grid nodes on the same grid line segment, the segment will be highlighted (its color is purple), LMC on the third grid node to define the impacted area. Next, release the Shift, then RMC to show options, and then select Line Attraction option, as shown in Figure 3. As a result, a set of nodes move forward to the gridline segment as shown in Figure 4.

Line Repulsion
The Line Repulsion option is the opposite way to the Line Attraction option in that the nodes in the defined area have a trend to go far away from the selected gridline. The steps to define the selected gridline and impacted area are similar to the Line Attraction option that is described above. After defining the impacted area, RMC to display options, select the Line Repulsion as shown in Figure 5.
