Recursive Multi-Time-Step Coupling Of Multiple Subdomains, Yukun An, Payton Lindsay, Xiaowo Wang, Arun Prakash

The Summer Undergraduate Research Fellowship (SURF) Symposium

The need for efficient computation methods for modeling of large-scale structures has become critically important over the past few years. Efficient means of analysis often involve coupling in space through domain decomposition and multi scale methods in time. The multi-time-step coupling method is a coupling method in time which allows for efficient analysis of large-scale problems for structural dynamics where a large structural model is decomposed into smaller subdomains that are solved independently and then coupled back together to obtain the global solution. For coupling of more than two subdomains that are solved at different timesteps, we employ recursive methods. …
