Unformatted text preview: facilitated by an unstructured grid may allow more accurate solutions. (3) Convergence CPU time : structured grid calculations usually take less time than an unstructured grid calculation because, to date, the existing algorithms are more efficient. 1 1 1 1 1 1 1 1 1 , 1 1 1 + + + + + + + ij i ij j i j i ij j i j i j i j i ( ) j i U , data stored in a 2D array ( ) i U data stored in a 1D array So, in order to calculate a residual for all, the neighboring states must be known. Structured : neighbors found by adding/subtracting 1 from cell indices. Unstructured : requires storage of celltocell pointers. More storage, slower execution of code. 12 14 11 13 15 10 0 2 9 1 3 8 6 4 7 5...
