MS5-01 - Advances in immersed/embedded/shifted/unfitted methods for computational fluid dynamics (CFD) and fluid-structure interaction (FSI)

Organized by: J. Yan (University of Illinois, Urbana-Champaign), G. Scovazzi, (Duke University), J. Evans (University of Colorado, Boulder), M. Hsu (Iowa State University), A. Korobenko (University of Calgary) and O. Colomés Gené (Delft University of Technology)
In modern engineering applications, much of the overall effort invested in finite element analysis is often devoted to geometric modeling and the transition from computer-aided design (CAD) to analysis-suitable models. Fictitious domain methods were introduced already in the early 1960s to avoid the need for body-fitted mesh generation. Since then, many variants of these appealing ap-proaches have been suggested, like embedded domain and immersed boundary methods or special implementations of the extended finite element method. They share with Isogeometric Analysis: "To support better design-through-analysis by closely coupling geometric modeling and numerical simulation." This mini symposium will focus on advanced immersed/embedded/unfitted meth-ods dedicated to CFD and FSI problems, including possible interactions with other physical fields (e.g., heat, multi-phase flow, etc.). The topics of this mini symposium will range from modeling aspects, including the coupling of analysis and CAD, mathematical analysis, stabilization, pre-conditioning, integration of cut cells, adaptivity, and implementational issues to the efficient solution of complex engineering problems. It will address low and higher-order unfitted discretization approaches, CutFEM, the Finite Cell Method, the Shifted Boundary Method (SBM), immersogeometric analysis, and other combina-tions with the Isogeometric Analysis. The goal is to bring together experts from academia and industry to discuss the most recent advances and emerging research directions in this field.
