The Adaptive PLIC-VOF Method with Overset Meshes

Abstract

Piecewise Linear Interface Calculation (PLIC) schemes have been extensively employed in the Volume of Fluid (VOF) method to capture the interface between water and air in marine applications. The Adaptive Mesh Refinement (AMR) is often adopted to increase the local mesh resolution dynamically within the cells which are close to or contain the interface. Dynamic overset meshes can be especially useful in applications involving component motions involving ship/offshore platform hydrodynamics, semi-submerged propellers, water entry/exiting, etc. An adaptive PLIC-VOF method with overset mesh for static objects has been introduced in the present study. Simulations are performed under the framework of OpenFOAM with a modified flow solver. Numerical simulations of two dam-breaking problems with overset meshes and adaptive PLIC-VOF method have been successfully performed. An extension of solid body movement supporting is currently ongoing.
