Ji-Ho Yang: Interface Jacobian Substructuring Algorithm for Multi-Component Dynamical Systems

This is a Master's thesis submission talk. Ji-Ho is advised by Tobias Neckel and BMW Research, New Technologies, Innovations.

Modern engineering products are becoming ever-increasingly more complex, involving many subcomponents from different subdomains of engineering. Performing numerical simulations for designing such products are not only computationally expensive, but also challenging due to their multi-physics nature. Although classical domain decomposition methods serve as highly robust and efficient means for design component integration, they are only able to handle Dirichlet-Dirichlet or Neumann-Neumann interface problems. In this thesis, we present an Interface Jacobian-based Substructuring method for general combination of interface constraints, including Dirichlet-Neumann coupling, and apply the method to linear dynamical systems. The core of this method is in generalization of formulation for solving interface problems by introducing both Dirichlet and Neumann constraints via interface Jacobian matrix. The algorithm is formulated and implemented on GPU in order to achieve real-time numerical simulation. Finally, the method is applied to an existing engineering product, and its computational performance is studied.
