Get better modeling capabilities with the integrated PIPESIM steady-state multiphase flow simulator

You can now model the flow of fluids for all your pipe networks using the integrated PIPESIM simulator, enabling you to examine and change specifications and view the results in the Symmetry process software platform.

Get better modeling capabilities with the integrated PIPESIM steady-state multiphase flow simulator

Within the unit operation, you can load a PIPESIM simulator model, modify its specifications and view the results within the Symmetry platform. In addition, it supports material port connections to sinks in the PIPESIM model, where non-compositional information from the PIPESIM simulator sinks is translated to a composition in the Symmetry platform ports. 

You can add signal port connections to examine variables in the PIPESIM simulator, as well as activate or deactivate sinks, sources, and chokes, and specify boundary conditions as well as the choke bean size. You can also inspect property profiles for nodes, branches, and flowlines in tabular and plot format.

Deeper analysis of separators within your overall system

Symmetry - analysis of separators

In a strategic step to enhance separation modelling capabilities within Symmetry, MySep has been integrated. The performance of a separator can be one of the largest factors in the overall operational performance of an asset.   MySep integration is available in both Steady State and Dynamics engines allowing the evaluation and understanding of the impact on the overall system. This integration will enable users to

  • obtain results faster and perform necessary changes from the MySep tab in the Separator unit operation and MySep Global Manager interfaces

  • perform more accurate rating and troubleshooting of your separation during Steady State or Dynamics simulations and gain a better understanding of how transient behaviour impacts the separation process.

Use Symmetry and MySep to predict separator performance and improve accuracy to help lead to better operations.

Symmetry 2020 Feature Highlights



Efficient and thorough safety design with Flaresim in Symmetry



HSE risks from flare operation can now be evaluated while designing or verifying the complete flare system. Users can verify that the system will protect the plant from overpressure and at the same time consider the effects on personnel and the public. This integrated workflow is the only one in the industry that verifies safety constraints for relief valves, piping and thermal radiation simultaneously across all scenarios. The flare system model is solved side by side with the model of the process equipment that it is protecting, facilitating safe and efficient data propagation.

  • Radiation isopleths

  • Noise levels at key locations

  • Temperature of exposed surfaces

  • Dispersion of emissions

  • Benefits of shielding

  • Assistance fluid for smokeless flare


Wide scale modelling eases the processes of data gathering and updating, so a single model can be used to ensure alignment with regulatory bodies and avoid penalties. For example, Symmetry offers centralized tracking of emissions from a variety of sources: flaring, venting, tank storage and transportation.

Repetitive calculations, the need to create different models and use of different software tools have been eliminated to save users time and improve results accuracy. Now you can launch the complete workflow from Symmetry 2020.

Keep your network alive, accurate and consistent



Take advantage of the new network designer tool that provides an element of automation to building pipelines. The Network Designer Mode within Symmetry will quickly allow you to create your pipelines from different sources, utilize GIS capabilities, and keep your network up to date and alive.

Symmetry platform aims for creating an environment with seamless integration to reach the most accurate results, by enabling the use of a network designer tool to build and update your system topology and add elevations with the use of ESRI and other technologies.

The innovative approach will give clear visibility when designing pipelines of any environmental concerns, pre-existing infrastructure, and even other pipelines that make it challenging to find a clear path. Ultimately, pipeline design with GIS is safer, more accurate and faster than traditional methods. When pipeline design is done without GIS, a significant amount of data must be compiled manually, and the entirety of the project may potentially be disrupted.

GIS awareness allows for a much better understanding of the actual field environment, which enables smarter decision making because it can expose potentially unforseen physical obstacles or other considerations.

The Network Designer has tools to allow the user to rapidly modify the topographical elevation profile of a pipe to honor such considerations such as road and river bores.

Users can construct networks interactively on the GIS canvas and quickly populate pipeline elevation profiles using a web service for both onshore and offshore environments. Large networks can also be constructed very quickly by importing and converting existing Shapefiles into pipeline systems, thereby eliminating the need to manually trace pipe profiles.

With the new Network Designer Mode, existing Unintended and potentially invisible pipe disconnects imported with shapefiles can be rapidly identified and connected with the click of a button, keeping your project up to date with important information.

Managing facilities with greater speed and more efficiency


Symmetry new release is focused on improving speed and efficiency in all major workflows available within the platform. The aim is to add seamless integration across the full spectrum to minimize the time users spend preparing information, creating models, running simulation and validating results. 

Symmetry 2020 helps users add value to their models with tools that facilitate both adding fidelity and performing wide-scale analysis.

  • Reduce capital cost of equipment and prevent plant upsets with the new slug catcher sizing utility. Users are able to size this key equipment quickly without compromising accuracy as the built-in sizing runs automatically in dynamics.

  • Save time and effort when setting up an LNG mixed refrigerant optimization, as the Pinch Utility calculates key values and can even track multiple pinch points.

  • All refinery reactors can solve with molecular reduced order models (m-ROM), allowing for optimization of refinery operation with rigorous, fast-solving models.

  • Higher fidelity on reciprocating compressors allows for more accurate studies when evaluating or optimizing energy consumption.

  • Blowdown valve and orifice sizing tools have been added with dynamics runs built in.
