However, standard fixed-step coupling often limits accuracy at the interface. Discretization errors distort signal behaviour between updates, and asynchronous events, such as safety threshold violations, are frequently detected with critical delays. In this paper we address these limitations by extending the FERAL simulation framework with a derivative-aware communication interface and an adaptive rollback mechanism. Our approach enables subsystems to extrapolate inputs continuously using First-Order Hold and allows the simulator to retroactively correct timing errors by re-simulating critical windows with high precision. We validated this methodology using an Adaptive Emergency Brake case study. Although the standard baseline simulation failed to prevent a collision due to an 891 ms detection delay, our proposed method achieved a safe stop with a response latency of &lt; 1 ms, effectively eliminating the synchronization error. Performance analysis confirms that this 99.8\\% accuracy improvement is achieved with only a marginal computational overhead, utilizing the hierarchical architecture of the framework to execute targeted rollbacks of only the affected components to the exact time of the event.<\/jats:p>","DOI":"10.7148\/2026-0470","type":"proceedings-article","created":{"date-parts":[[2026,6,30]],"date-time":"2026-06-30T16:55:14Z","timestamp":1782838514000},"page":"470-479","source":"Crossref","is-referenced-by-count":0,"title":["Minimizing discretization errors and event impacts in continuous system simulations"],"prefix":"10.7148","author":[{"given":"Priom","family":"Biswas","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dishant","family":"Mahajan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Kuhn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pablo Oliveira","family":"Antonino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philipp","family":"Zech","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4144","published-online":{"date-parts":[[2026,6,23]]},"event":{"name":"40th ECMS International Conference on Modelling and Simulation"},"container-title":["ECMS 2026 Proceedings edited by Filippo Sanfilippo, Florenc Demrozi, Fabio Sgarbossa, Mohammad Poursina"],"original-title":[],"deposited":{"date-parts":[[2026,6,30]],"date-time":"2026-06-30T16:55:18Z","timestamp":1782838518000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.scs-europe.net\/dlib\/2026\/ecms2026acceptedpapers\/0470_simo_ecms2026_0014.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,6,23]]},"references-count":0,"URL":"https:\/\/doi.org\/10.7148\/2026-0470","relation":{},"subject":[],"published":{"date-parts":[[2026,6,23]]}}}
