A three-dimensional hybrid finite element -- spectral boundary integral method for modeling earthquakes in complex unbounded domains
Gabriele Albertini, Ahmed Elbanna, David S. Kammer
We present a 3D hybrid method which combines the Finite Element Method (FEM) and the Spectral Boundary Integral method (SBIM) to model nonlinear problems in unbounded domains. The…

On the use of Multigrid Preconditioners for Topology Optimization
Darin Peetz, Ahmed Elbanna
Topology optimization for large scale problems continues to be a computational challenge. Several works exist in the literature to address this topic, and all make use of iterative…
