This seminar from the FEM@LLNL Series features Patrick Zulian from Università della Svizzera italiana / UniDistance Suisse presenting research on immersed domain approaches for fluid-structure-contact interaction problems. Explore the computational techniques for fluid-structure interaction (FSI), comparing boundary-fitted and non-boundary-fitted mesh approaches. Learn about an innovative immersed domain approach for solving fluid-structure-contact-interaction (FSCI) problems, utilizing dual Lagrange multipliers within nonlinear solution procedures. The presentation showcases two practical applications: a bio-prosthetic heart valve simulation modeling interactions between blood, valve, and aortic wall; and a diaphragm pump simulation featuring contact interaction between an elastic valve and valve seats. This technical talk, sponsored by the MFEM project, provides valuable insights for researchers and practitioners interested in finite element methods and their applications in complex interaction problems.
