1.11.7 Water sloshing in a pitching tank

Product: ABAQUS/Explicit  

Problem description

Adaptive meshing

A single adaptive mesh domain that incorporates the water is used for each model. A sliding boundary region is used for the contact surface definition on the water (the default). Because of the large amounts of shearing induced by the sloshing motion, the frequency and intensity of adaptive meshing must be increased to provide a smooth mesh. The value of the FREQUENCY parameter on the *ADAPTIVE MESH option is reduced from the default of 10 to 5, and the value of the MESH SWEEPS parameter is increased from the default of 1 to 3.
