Meshes.RegularCoarsening — Type
RegularCoarsening(f₁, f₂, ..., fₙ)Coarsen each dimension of the grid by given factors f₁, f₂, …, fₙ.
Examples
coarsen(grid2D, RegularCoarsening(2, 3))
coarsen(grid3D, RegularCoarsening(2, 3, 1))grid = CartesianGrid(100, 100)
# refine three times
cor1 = coarsen(grid, RegularCoarsening(2, 2))
cor2 = coarsen(cor1, RegularCoarsening(3, 2))
cor3 = coarsen(cor2, RegularCoarsening(2, 3))
