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.

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.
