Wave in deck loads using Lagrangian Momentum Absorption (LMA) scheme

When the water surface elevation exceeds the deck elevation and inundates the deck of fixed offshore structures, the resulting loads which are known as wave-in-deck loading leads to a step change in the loads acting on the structure. Given its importance, for predicting WID, a number of approache...
