Simulation of Moving Bodies Using a Meshfree Method

Comparing to conventional CFD methods, meshfree methods have a great potential in dealing with moving boundary problems as mesh points can move in a truly arbitrary manner without the concern of ruining the integrity of the computational mesh. In the present work, we develop a meshfree solver to compute flow problems with moving boundaries. The initial set of points is generated with an automated mesh generator given user defined geometries. The mesh generator can also modify the point set to allow the geometrical bodies to move based on user prescribed motions. The developed tool is tested with several stationary and moving boundary problems. The potential of the meshless solver for moving boundary problems is successfully demonstrated for relatively complex geometries.
