Multirate time-integration methods [3–5] appear to be attractive for initial value problems for DAEs with latency or multirate behaviour. Latency means that parts of the circuit are constant or slowly time-varying during a certain time interval, while multirate behaviour means that some variables are slowly time-varying compared to other variables. In both cases, it would be attractive to integrate these slow parts with a larger timestep than the other parts. This saves the computational workload while the accuracy is preserved. A nice property of multirate is that it does not use any linear structure, in contrast to MOR, but only a relaxation concept. If the coupling is sufficiently monitored and the partitioning is well chosen, multirate can be very efficient. [ABSTRACT FROM AUTHOR] |
