Fluid-structure interaction algorithm for an elastic structure with large deformations
Original language description
This contribution introduces a fluid-structure interaction (FSI) algorithm where the structure is considered elastic. One of the main requirements for the FSI algorithm is a high level of modularity, meaning that the fluid and structure solvers are independent of each other. For this reason, a partitioned approach was adopted with the option of either weak or strong coupling. The fluid dynamics is simulated using the discontinuous Galerkin finite element method whereas the structure dynamics is simulated using the continuous Galerkin finite element method. The structure is modelled by a non-linear mathematical model which allows for large deformations. The meshes for both the fluid and the structure are non-uniform and mutually non-conforming, in other words the meshes do not need to align on the fluid-solid interface. This allows for simple and flexible generation of meshes. The transfer of data between the fluid and the structure is carried out by interpolation with radial basis functions. The fluid and structure solvers are validated independently on a couple of benchmarks and the coupled FSI solver is tested on the well-known Turek-Hron benchmark.
