While the numerical methods for single-physics problems are well-researched and generally well-established, robust solutions for coupling disparate physics are lacking. Many methods exist for some classes of fluid-structural interactions (e.g. aero-structural), but the solutions developed there are not necessarily applicable to other couplings, such as thermal-mechanical or biological applications. In this minisymposium, we encourage submissions that discuss advances in coupling multiple sets of physics, including thermal transport, fluid dynamics, solid mechanics, species transport, chemistry, electrical transport, magnetics, and others. Coupling techniques may range from monolithic (single-matrix) coupling using block or other multiphysics preconditioning, to loose-coupling based on operator splitting techniques between different codes or numerical formulations. We also encourage application-focused submissions that discuss either techniques/methods that have worked well or attempts where challenges still exist.
