Abstract
High fidelity modeling of complex multiphysics systems poses a challenging problem in many respects, and as the complexity of problems of interest increases, so too must our computational power and solution method efficiency. Recently, a preliminary ability to model boiling water reactors was added to the VERA reactor simulator code package. This has raised questions regarding how to solve problems of this type both efficiently and robustly. In this work, Anderson acceleration is applied to assist in multiphysics coupling in an attempt to improve performance over previously used methods.
