A three dimensional simulation method based on the marker cell concept to analyse liquid sloshing in the tanks of prismatic geometry was developed by the authors. In this study, in order to simulate liquid sloshing inside the tanks with more general geometry, the numerical treatment of the boundary conditions which correspond to the curved tank walls is modified. This improved version of the method is presented in this paper. Liquid slosing inside a cubic and a cylindrical tank is simulated. The time histories of the free surface position and the dynamic pressure are obtained. The accuracy of the present method is verified by comparing the computed results with the experimental ones. These comparisons also show that the present method is able to simulate swirl motion, of the liquid inside a cubic and a cylindrical tank, which is difficult to be analysed by the conventional methods.
