Daccosim NG: co-simulation made simpler and faster

Abstract

This paper introduces the last evolution of Daccosim co-simulation environment, with Daccosim NG developed in 2018. Main features of Daccosim NG are described: en-hanced Graphic User Interface and Command-Line In-terface, algorithm and mechanism of co-simulation, co-execution shell, software architecture designed for bothcentralised and distributed architectures, aggregation of aco-simulation graph into a Matryoshka FMU, and declar-ative language to design large scale co-simulation graphs.A new industrial use case in simulation of energetic sys-tems is also introduced, and first performances of Dac-cosim NG on multi-core architectures are analysed.
