A finite-element/boundary-element method for three-dimensional, large-displacement fluidstructure-interaction
A FEM-discretized KirchhoffLove shell is coupled with a BEM-discretized Stokes flow. A new KL shell formulation which bypasses an auxiliary parametrization is presented. The Lagrange multiplier for incompressibility can be interpreted as a total pressure. Smooth b-spline and subdivision surfaces discretizations are compared. X-large deformations are realized in numerical tests by avoiding volume meshing/remeshing.
