Parallel implementation of immersed boundary adaptive FEM or how to avoid mesh generation in a mesh-based method
Original language description
Finite element method (FEM) typically relies on computational meshes composed of elements forming a nonoverlapping partition of the computational domain. However, generating these meshes of suffcient quality can be challenging and time-consuming, especially for very complex geometries used, e.g. in 3D printing. As a potential remedy, ideas of the immersed boundary method have been incorporated into FEM. We present a parallel implementation of an immersed boundary adaptive FEM. In order to achieve suffcient resolution at the boundary, local mesh re nement driven towards boundary is used. For large meshes distributed over a large number of processors, the resulting systems have to be solved by parallel iterative solvers. We present the method and demonstrate its performance for a complex problem of linear elasticity with meshes re ned adaptively towards the area with the largest stress for achieving better accuracy within these regions.
