This paper presents an application algorithm of CIVA method, which is so flexible as to enable to integrate the CIP, gridless and particle method, to incompressible fluid simulation. The CIVA-based algorithm that is combined with the methods such as the control volume method, the MAC method, the automatic unstructured mesh generation method makes it possible to simulate many kinds of problems having complex geometries and phenomena with a high accuracy. To confirm the possibility, numerical analyses for some benchmark problems were executed. The results showed that the method achieves high accuracy and has high flexibility even for the flows of high Reynolds number, complicated geometries, moving boundaies and free surface.
