Implementation of Immersed Finite Element Method for Fluid-Structure Interaction Applications

N. Nama [1], T. J. Huang [1], F. Costanzo [1],
[1] Department of Engineering Science and Mechanics, Pennsylvania State University, PA, USA

Fluid-structure interaction (FSI) refers to a class of problems in which the motions of fluid and solid are coupled. FSI is of great significance in many applications such as aero-elasticity, biomechanics, and design of various engineering systems. Typically, the multiphysics involved in ... Read More
