Description

Method and system applied to industrial simulation platform
Technical Field
The invention relates to the technical field of computers, in particular to a method and a system applied to an industrial simulation platform.
Background
In the 4.0 th era of industry, simulation occupies a core position, and the core elements of the simulation are industrial simulation software and ultra-strong computational power. At present, most industrial simulation operations are in a single machine mode, and a user carries out simulation operations on a machine or a workstation. For enterprises, the single machine mode has several problems, firstly, the cost of software and hardware is high, expensive commercial simulation software authorization and a large number of machines or workstations need to be purchased, and the operation and maintenance costs of scattered machines or workstations are also high; secondly, for the simulation requirements of increasing scale and complexity, single machine resources cannot be dispatched and used in a centralized manner, effective computational support cannot be provided for large-scale parallel simulation, and the resource utilization efficiency is low. The cloud mode can realize centralized management and scheduling of software and hardware resources, and an industrial simulation cloud platform is gradually raised.
Most industrial simulation cloud platforms continue the cloud computing thinking of the internet, and only simply carry out centralized scheduling on software and hardware resources, and do not really solve the actual requirements of industrial simulation. The current industrial simulation cloud platform only provides a simulation solving function, a user needs to upload a simulation model for calculation solving, a download result is post-processed on a personal computer after calculation is completed, the process may need to be repeated for many times, the whole simulation flow operation is cut off, and the working efficiency of the user is seriously reduced. And the simulation solving process can not monitor the simulation state in real time, and can not terminate and adjust the simulation model in time, thus causing a large amount of invalid calculations.
In addition, at present, industrial simulation software integrated by an industrial simulation cloud platform is basically some commercial universal simulation software with few varieties. The industrial fields are various, the industrial simulation requirements are different, the general commercial simulation software can only meet the simulation requirements of partial industries or fields, the applicability to the subdivided fields is not very high, and the simulation requirements of a large number of subdivided fields are ignored. In addition, the universal simulation software has higher requirements on the capability and experience of users, but most of small and medium-sized enterprises in China have no simulation capability, so that the commercial simulation software cannot be used for product design and development.
