Abstract: By employing the nonlinear multimodal technique, the paper proposes an algorithm and computer code (SLOSHER) for derivation of asymptotic [third-order] nonlinear modal systems describing the nonlinear liquid sloshing in a vertical circular cylindrical tank. Applicability of the code is demonstrated for the benchmark modal system by Lukovsky (1990). A novel nonlinear modal system which takes into account most principal third-order modes is derived.
