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.
