Title: Simulating fluid flow at a moving boundary

Abstract: A method of simulating fluid flow in a three-dimensional volume with a moving boundary is presented. The moving boundary is provided within a computational fluid dynamics (CFD) mesh. The CFD mesh includes mesh points defining three-dimensional mesh cells. Locations of the mesh points at the moving boundary are revised predicated on known motion characteristics thereof such that the CFD mesh undergoes distortion near the moving boundary. The distortion is minimized using an elastic deformation model that does not involve dimensional physical parameters. As a result, a revised CFD mesh is generated. A fluid flow simulation is then computed for the three-dimensional volume using the revised CFD mesh.
