A Moving Overset Grid Method for Simulating Elastic Interfaces in a Viscous Fluid
Abstract
We study the dynamics of elastic interfaces in a viscous incompressible fluid using a new numerical technique based on moving overset grids. The key idea is to use thin, body-fitted grids that move and deform with moving boundaries, while using fixed Cartesian grids to cover most of the computational domain. Large scale deformation of the flow boundaries can be handled without a global regridding, and in a computationally efficient way. Numerical results will be presented, and compared with other techniques for this class of problems.
