Restarting algorithms for simulation problems with discontinuities

Mohammadi, Fatemeh LU ; Arévalo, Carmen LU and Führer, Claus LU (2014) 10th International Modelica Conference In Linköping Electronic Conference Proceedings p.819-826
Abstract
Modelica has in its language support for describing discontinuities; so-called events. Modern integrating environments; like Assimulo; provide elaborated event detection and event handling methods. In addition; the overall performance of a simulation of models with discontinuities (hybrid models) depends strongly on methods for restarting integration after event detection. The presented paper reviews two restarting methods; based oRunge--Kutta starters for multistep methods; and presents first experiments on a hybrid system described in Modelica and simulated by JModelica.org/PyFMI and Assimulo.
