Asynchronous and composable distributed co-simulation engine design for cloud-based industrial CAE software

Abstract

The industrial Internet can be seen as a combination of industrial software, sensors, networks and cloud platforms. Among them, industrial software is the key to data utilization while the cloud platform provides support for Industrial Internet. Through "visualization", "structuring", "modeling and simulation" and other means, industrial software can help solve the design and manufacturing problems of industrial products. But the difference between industrial Internet and traditional Internet lies in the different application scenarios and data characteristics, which also leads to the different emphasis of system architecture design. Considering the needs of high concurrency and huge data processing, the distributed system must provide high performance of communication and computing services. In addition, with the continuous expansion of the simulation model and the simulation scale, it becomes particularly significant to reduce the model development complexity and improve maintainability and flexibility. To make the distributed co-simulation engine more highperformance, we propose an asynchronous communication module as the underlying architecture of the distributed engine. Then combining the discrete event system specification and Actor model, a layered architecture has been proposed, which implements the modular programming of behavioral model by functional programming. Based on the architecture mentioned above, a distributed CAE cloud platform is proposed, which is hierarchical, modular, composable and reusable.
