Enhancements to Symmetry software’s built-in optimizer will make it easier for experts and non-experts to understand and influence the solver’s performance. A new plot helps users to visualize the optimization path, including progress, changes in manipulated variables, and constraint boundaries. A detailed log provides additional transparency into the optimization method behavior. Users can take greater control over the optimization process with new options for specifying termination criteria, problem scaling, and perturbation sizes. Enhanced status messages ensure a more efficient and user-friendly experience, helping users achieve optimal results with ease.
By automatically generating backup files of working cases, Symmetry software’s new auto-backup option reduces the risk of making irreversible changes to the model, as well as potential losses from unexpected events like system crashes. The user can customize auto-backup behavior by modifying both the minimum time between backups and the maximum number of case versions to save. Backup files are saved alongside the active case for easy access and smooth recovery, enhancing productivity and peace of mind.

Symmetry software’s 64-bit installation can now apply predictions from the Olga-S flow model for high-fidelity, steady-state pressure drop calculations in all workspaces. Olga-S is the steady-state prediction routine, or point model, from the Olga™ dynamic multiphase flow simulator. It is a mechanistic model that simulates each of the flow regimes in multiphase flow and determines the main flow properties. The new vendor-agnostic installation of Olga-S is acquired and licensed through SLB.

Activity coefficient and heat of absorption parameters are also exposed for user tuning.
For R&D into novelty solvent formulations and additional tuning to experimental data, Amines 2 offers the flexibility to incorporate user-defined amines and custom reactions beyond those available in the Symmetry software database. Contact us for more information on these advanced features.
A newly added “Time-based analysis” tool enables modeling of processes for long-term planning and evaluations. Such steady-state time-based studies are especially relevant in green hydrogen production, where factors like the power available to an electrolyzer, equipment decay, costs, and pricing fluctuate meaningfully over time. A technoeconomic evaluation or operational planning study can be conducted by first specifying how key input parameters change over time, and then tracking pertinent calculated values through a batch run of the simulation. Large input data sets (for example, a weather forecast) can be imported through a csv file and managed in a data source manager for reuse in multiple studies. Time-tracked results are easily exportable as a csv file for further analysis and custom reporting. These productivity tools can thus ease decision making on the economic feasibility and optimal operation of a green hydrogen project.
The pipe workspace has been enhanced to enable direct specification of pressure at network sources. Just as in dynamics, steady-state network sources now support pressure specification as an alternative to flow. In situations where a fixed pressure best represents field metering and control, this specification eliminates the need for controllers to be added to the network, significantly improving usability, solver speed and robustness. Pressure may be specified at all, or a subset of, sources.
A new hybrid block unit operation facilitates integration between rigorous physics-based models and high-performance AI/machine learning (ML) surrogate models.

New workflows empower users to quickly evaluate the performance of a surrogate model, validate its predictions with comparison to a physics-based counterpart, and use the power of the resulting hybrid model for high-performance optimization and process studies.

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 unforeseen 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.
