NEM and MFEM Simulation of Interaction between Time-dependent Waves and Obstacles

Abstract

Fundamental research challenge of structural integrity and construction resistance while interacting with fluid or gas is of high importance when estimating their efficiency and lifetime. The paper presents the simulation results of interaction between incompressible ideal fluid and an escarpment at the bottom, and interaction between viscous incompressible fluid and an obstacle above fluid surface. Flow patterns at different times and chronograms of hydrodynamic loads on solid walls of computational domain, horizontal and vertical obstacles are displayed.
