A Comparison of Multirate Co-Simulation Techniques for Field-Circuit Coupled Problems
This work provides practical guidelines for selecting multirate co-simulation methods in field-circuit coupled problems, but the results are incremental and domain-specific.
The paper compares three multirate co-simulation techniques for field-circuit coupled magnetoquasistatic simulations, testing three value-exchange variants on two benchmark problems. It provides convergence behavior for Implicit Euler and Trapezoidal Rule and offers practical guidelines.
This paper compares three different multirate splitting approaches for the application on field-circuit coupled magnetoquasistatic simulations. For these methods, again three different variants for exchanging values between the field and circuit are tested, namely voltages, currents and flux correction terms. All scenarios are applied on two different benchmark problems, i.e. a coil inductor and transformer model coupled to different circuits. The convergence behavior of different time steppers (Implicit Euler and Trapezoidal Rule) is determined for all possible settings, and guidelines for practical applications are derived.
