Hi,
When develop the 2-D flood modelling, there are tow methods, namely CIP method and upwind scheme in the “calculation condition- Others- Finite differential method for advection terms “. What are the differences in these two methods and which one i need to select for simulating flood events. Your early replies will be highly appreciated. Thanks in advance.

    In “Nays2DH_SolverManual_English.pdf”, This is a high-order finite-difference method. By using a cubic polynomial as an interpolation function, numeric diffusion is reduced,
    thus enabling high-precision local interpolation.

    Thank you very much for the reply. I am asking about finite differential method for NAYS2D Flood solver. There are two finite differential methods such as CIP method and upwind method in NAYS2D Flood solver and i need the explanation on what differences in these two methods and which one i need to select for simulating flood events. Your early replies will be highly appreciated. Thanks in advance.

    In flood calculation, I think there is not much difference between the two methods.
    Please compare the calculation results of both methods.
