For the traditional computing codes in the three core steps of pre-processing,calculation and post-processing,in which the pre-processing has high professional requirements for users and poor intuitiveness;in the calculation process,users need to handle multi-disciplinary computing codes are designed to verify the cumbersome data transfer;in post-processing,the third-party post-processing software is required for re-processing analysis.This paper implements multidisciplinary joint simulation platform,integrating the three cores of pre-processing,calculation and post-processing.Among them,the pre-processing procedure enables fast,refined modeling,and so on.The calculation procedure implements functions such as calculation program operation control,instruction analysis,task scheduling,and operation flow control.The post-processing procedure provides functions such as the cloud map.Finally,through the establishment of a two-pipe model to verify relevant functions of the platform.Through verification,the platform breaks through the key technologies such as rapid refinement design modeling and online debugging of systems and equipment,and provides an efficient and intuitive technical means for the rapid generation,evaluation,verification and optimization of the performance design of reactor systems.
