Fictitious Domain Methods

2:00 PM-4:00 PM
Room: Sidney Smith 2102

This minisymposium will highlight current research on the development of fictitious domain methods for the simulation of physical phenomena in complex geometries. In these methods, also called domain imbedding methods, domain boundaries are imbedded in some auxiliary domain the shape of which is simple and can be easily meshed. Coupled with the finite element method, the fictitious domain methods have proven efficient for the numerical treatment of domains containing moving bodies. It has been used, for instance, to simulate fluid flow inside an industrial mixer equipped with intermeshing impellers and to optimize the shape of a NACA0012 airfoil. This minisymposium will focus on applications as well as the development of new methods. It should be of interest to any researcher concerned with the simulation of physical phenomena involving complex geometries.
