软件简介
（Symmetry）是一种过程软件平台，是一个全面的模拟器，可以捕获模型的各个方面，从油藏到产品分销。Symmetry平台是使用VMG经过行业验证的仿真技术构建的，该技术已经过优化，可以根据您的工程需求进行扩展。Symmetry平台独特地集成了现场，管网，加工厂和火炬系统的建模，可提供前所未有的协作水平。Symmetry平台在设计时考虑了灵活性。它可以用来为特定的应用程序建模或创建一个综合模型，该模型可以从现场跨越不同类型的设施。一切都使用一致的热力学引擎。
仿真模型中的每个流程图都可以在稳态或动态条件下求解，并且不同类型的流程图为处理设施，管网或火炬系统的模型提供了量身定制的工作空间。管道和火炬工作空间中的稳态求解器根据规格提供了压力流网络求解器和顺序求解器的独特组合。Symmetry平台的量身定制的工作区包括：VMGSim（世界一流的设施和工厂过程仿真）；管道（复杂管网的严格动态和稳态多相建模）；Flare（具有集成PSV，网络标题和堆栈设计的全包式救济系统分析）；现场（具有预测功能的完全集成的气藏和多相采集系统）。
VMGSim（过程），管道和火炬工作空间共享相同的过程平台，因此它们共享相同的广泛工具集，包括回归，优化器，经济性，连通性和流体特性。热力学引擎在整个模拟器中是一致的，并成为集成模拟模型的关键组成部分。根据特定的功能和视图量身定制工作区，以促进通用工作流并提高生产率。Symmetry平台的灵活设计使用户能够为从概念设计到优化和消除瓶颈的各种应用和用途创建仿真。Symmetry平台的多功能性使其成为桌面工作或工业4.0实施的理想工具。
Symmetry, a process software platform, is a comprehensive simulator that captures all aspects of your models from reservoir to product distribution. The Symmetry platform is built using VMG’s industry proven simulation technologies that have been optimized to scale to your engineering needs. The Symmetry platform uniquely integrates the modeling of fields, pipe networks, process plants and flare systems, providing an unprecedented level of collaboration. The Symmetry platform is designed with flexibility in mind. It can be used to model a specific application or to create a comprehensive model that may span from the field through different types of facilities. Everything using a consistent thermodynamic engine. If you are a VMGSim user you will feel right at home since the Symmetry platform builds upon familiar workflows and a powerful core of process simulation technology that comes from VMGSim.
Each flowsheet in a simulation model can be solved in steady state or dynamics, and different types of flowsheets provide tailored workspaces for models of processing facilities, pipe networks or flare systems. The steady state solver in the pipe and flare workspaces provides a unique combination of a pressure flow network solver and a sequential solver depending on the specifications. The Symmetry platform’s tailored workspaces include: VMGSim (World-class process simulation for facilities and plants); Pipe (Rigorous dynamic and steady-state multiphase modeling for complex pipe networks); Flare (All-inclusive relief system analysis with integrated PSV, network header and stack design); Field (Fully integrated gas reservoir and multiphase gathering system with forecasting functionality).
The VMGSim (Process), Pipe and Flare workspaces share the same proces platform therefore they share the same extensive set of tools including regression, an optimizer, economics, connectivity and fluid characterization. The thermodynamic engine is consistent across the entire simulator and becomes a critical component of an integrated simulation model. Workspaces are tailored with specific features and views to promote common workflows and increase productivity. The flexible design of the Symmetry platform enables users to create simulations for a wide variety of applications and uses, from conceptual design to optimization and debottlenecking. The versatility of the Symmetry platform makes it the perfect tool for desktop work or for Industry 4.0 implementations.
