My cfd code is based on finite volume method. For example in (du/dy)2 how should I descritize it? It is computed in center of each cell so I face like this: (du/dy)*2~\|du/dy\|\|du/dy\| that using Green theory in each cell: \|du/dy\|={- $\sum$ [u(i)dx(i)]}/area of cell* but when I implement, the Fortran code is terminated by math (M6101) error. tanx.
