文摘

A dynamic local mesh coarsening/refinement (LCR) method is newly developed for sloshing simulations with unstructured mesh. Results from adaptive grids agree well with existing experimental and numerical studies. Present adaptation scheme reduce the computational cost at-least by half. Present numerical approach can handle almost all the filling ratios of practical importance.
