On decoupled time step/subcycling and iteration strategies for multiphysics problems
SUMMARY This work investigates partitioned iterative solution of coupled multiphysics systems including subcycling time-stepping strategies for decoupled subsystems in conjunction with a proportional-integral-derivative feedback control algorithm for adaptive time-step selection. Some basic algorithms are proposed and the total computational effort to integrate to steady state is compared for a representative coupled flow and heat transfer problem to illustrate the approach and assess performance efficiency.
