A novel approach to fluid-structure interaction simulations involving large translation and contact
Daniel Hilger, Norbert Hosters, Fabian Key +2
In this work, we present a novel method for the mesh update in flow problems with moving boundaries, the phantom domain deformation mesh update method (PD-DMUM). The PD-DMUM is des…

Combining Boundary-Conforming Finite Element Meshes on Moving Domains Using a Sliding Mesh Approach
Jan Helmig, Fabian Key, Marek Behr +1
For most finite element simulations, boundary-conforming meshes have significant advantages in terms of accuracy or efficiency. This is particularly true for complex domains. Howev…
