Symmetry by VMG
Symmetry is a comprehensive simulator that captures all aspects of your models from reservoir to product distribution. Symmetry is built using VMG’s industry proven simulation technologies that have been optimized to scale to your engineering needs.
Symmetry is in its final beta cycle and we are still looking for feedback. Contact us to get early access to all of the functionality that Symmetry offers.
What is Symmetry?
Symmetry uniquely integrates the modeling of fields, pipe networks, process plants and flare systems, providing an unprecedented level of collaboration. Symmetry 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 Symmetry 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.

Symmetry’s tailored workspaces include:
- Process: World-class process simulation built from VMGSim for facilities and plants
- Pipe: Rigorous multiphase pipe network for complex and looped 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 Process, Pipe and Flare workspaces share the same simulation environment 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 Symmetry enables users to create simulations for a wide variety of applications and uses, from conceptual design to optimization and debottlenecking. The versatility of Symmetry makes it the perfect tool for desktop work or for Industry 4.0 implementations.
