Abstract:
We develop a new stabilized XFEM based fixed-grid approach for the transient incompressible Navier-Stokes equations using cut elements. Our framework is based on a new flexible strategy to handle several degrees of freedom (DOFs) at nodes required for complex shaped embedded meshes as they occur for fixed-grid fluid-structure interaction problems. Boundary conditions on embedded boundaries are imposed weakly using a Nitsche type approach. Ghost-penalty terms for velocity and pressure are ad...     »
