• Solutions are obtained at each cell.Solutions are obtained at each cell.

• Solutions cover scalar and vector Solutions cover scalar and vector variables.variables.

• Distribution of Scalar variables can be Distribution of Scalar variables can be visualized using contour plot. Contour visualized using contour plot. Contour utilized a line to indicate points with utilized a line to indicate points with same scalar values. Flood is also used same scalar values. Flood is also used to visualize contour.to visualize contour.
