J0102-2-2 Voxel Solid Interaction Scheme for Computational Biomechanies

Abstract

A solid-solid-fluid interaction scheme is developed for biomechanics simulation. The scheme is based on full Eulerian formulation, which is familiar with medical voxel data. Both solid arid fluid are modeled as an incompressible material and one governing equation treats equations by using the volume fractions of the materials. Both FEM and FDM are used for space discretization of fixed structural mesh. PLIC (Piecewise Linear Interface Calculation) method is used to capture the material interfaces with high accuracy and to impose boundary conditions on the material interfaces.
