Consider the two-dimensional wye of Fig. P15–27. Dimensions are in meters, and the drawing is not to scale. Incompressible flow enters from the left, and splits into two parts. Generate three coarse grids, with identical node distributions on all edges of the computational domain: 

(a) Structured multiblock grid, 

(b) Unstructured triangular grid, 

(c) Unstructured quadrilateral grid. 

Compare the number of cells in each case and comment about the quality of the grid in each case.
