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: enhanced Graphic User Interface and Command-Line Interface , algorithm and mechanism of co-simulation, co-execution shell, software architecture designed for both centralised and distributed architectures, aggregation of a co-simulation graph into a Matryoshka FMU, and declarative language to design large scale co-simulation graphs. A new industrial use case in simulation of energetic systems is also introduced, and first performances of Dac-cosim NG on multi-core architectures are analysed.
