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.

Whats New
v2020.3 (September 2020 - Symmetry Update Release)

Thermodynamics
-o Hydrate inhibitors (Methanol, Ethylene Glycol, Triethylene Glycol, Ethanol, Glycerol, 1,2-Propylene Glycol and 1,3-Propylene Glycol) are now allowed to be part of the Aqueous phase
-x Fixed compounds containing ";" in their names. Compounds fixed are:
-1,1':2',1''-terphenyl, 4'-phenyl-
-1,1':2',1''-terphenyl, 3'-phenyl-
-2-BUTENEDIOIC ACID (Z)-, DIPROPYL ESTER
-Fixed label mismatch in hydrate parameters for APRNG2 and APRNG
-Fixed sub-flowsheets not using the Global Liquid Reference T and P. They were using the parent flowsheet settings

Flare Workspace
-Fixed issues related to missing updates when importing cases with networks or scenarios
-Fixed issue with flare XML file import adding flare tip curve points out of order
-Fixed issue with flare XML file import not recognizing # as a special character

Pipe Workspace
-Added support for check valve functionality for valves in networks with multiple sinks and loops
-Added warning to tabular IPR when solved operating point is outside the specified data range
-Enabled network specifications to be passed from calculated values of networks in the same flowsheet, including solving recycles between connected networks.

Network Solver
-Added 2-K (Hooper) and 3-K (Darby) K methods for supported pipe fittings in steady state
-Added support for flow specifications (Mole, Mass and Std Liq Vol) at sinks
-When the network is solving with PH flash, it will now solve all devices within the network with PH flash (including valves with Cv specifications, orifice meters, rotating equipment, and flare tips)
-Fixed fitting diameter when changing a pipe diameter not changing to new diameter
-Fixed phase calculation errors when initializing IPR curve
-Fixed issue where results for zero-flow legs in a network may not be calculated with zero flow but instead show values from a previous solver iteration, which could result in consistency errors
-Improved separator stability in network solver when running with low vapor flows in networks with a single stack and no loops

Extensions and Links
-New OLGA Link. The OLGA Link allows connecting OLGA models with Symmetry. This integration allows for wide-scope integrated models where transient behaviour of gathering networks, distribution systems and facilities can be studied under the same environment.

Flaresim
-Fixed files association for .fsw and .fsz files to the Flaresim executable in the Symmetry installation

GIS Network tool
-Fixed importing GIS shape files when they contain extra information in UTM zone field
-Fixed crash when renaming wells with more than 29 characters
-Fixed conversion of GIS model to pipe for cases where the demand names were longer than 19 characters

Unit Operations
-Exposed a k value for pressure drop calculation based on mass flow for heater, cooler, air cooler, heat exchanger and multisided heat exchanger.
-Property Table - New option to invert the Z-density and phase plots
-Property Table - Added option to generate, view and export OLGA Fluid Tables which can be imported into OLGA simulation runs. Fluid tables can also be exported in Fixed (Legacy) format for users of OLGA-ROCX
-Property Table - Added option to generate, view and export PIPESIM Fluid Tables which can be imported into PIPESIM simulations. Fluid tables can also be exported in Revision A (Legacy) format
-Towers - Improved solve time of towers with pump arounds or side strippers
-Heat Exchanger - Improved default simple flash model building criteria to speed up heat exchangers with pressure drops over 15-20 psi, and exposed criteria to validate and tune
-Valve - Improved valve convergence and consistency validation when solving in a network at choked flow
-Heat Exchanger - Fixed PSF file exporting to handle multiple property packages
-Heat Exchanger - Fixed multisided heat exchangers to use flash cache. This speeds up iterations when solving with more than 2 sides and UA specifications
-Multi-Sided HX - Fixed a crash in dynamics when the top and bottom layer are the same
-Pipe Segment - Fixed fitting angle not resetting when changing fitting type
-Refinery Reactors - Fixed visibility issue for the Catalyst and Thermal Database in CCR, FCC, HCC and Hydrotreater

Miscellaneous
