Refine Grid Block

The Refine Grid Block tool increases the resolution of the specific grid block. It operates by multiplying the existing number of cells in the current grid with (IC, JC) independently.

Select two gird nodes by holding the SHIFT key to define the grid block. RMC and select Refine Gird Block. Then, the Grid Block Refinement tab will appears. It is able to set the I and J refinement factor separately.
