We present a numerical scheme for fluid–structure interaction based on hierarchical B-Spline grids and fictitious domain/distributed Lagrange multipliers. The incompressible Navier–Stokes equations are solved over a Cartesian grid discretised with B-...

This contribution investigates the performance of a least-squares finite element method based on non-uniform rational B-splines (NURBS) basis functions. The least-squares functional is formulated directly in terms of the strong form of the governing... Read More about NURBS based least-squares finite element methods for fluid and solid mechanics.
