Aquanuity, Inc., the leader in strategy-led simulation-powered water infrastructure digital twin software, today announced the fourth quarter 2024 addition of a new state of the art computationally efficient implicit hydraulic solver for AquaTwin Sewer and AquaTwin Sewer 2D that pushes the limits of sanitary and storm sewer analysis. It further substantiates Aquanuity’s steadfast commitment to delivering value-driven geocentric innovation to its customers.

The new method is an advanced staggered-grid implicit finite difference scheme (SGIM) for solving the one-dimensional Saint-Venant equations in sewer/channel networks. It solves for link flows and nodal heads simultaneously at each time step by embedding the solutions to the Saint-Venant equations into a system of implicit linear equations. This ensures stability, accuracy, and computational efficiency. Furthermore, the method utilizes recurrence relations significantly reducing the size of the solution matrix and accelerating run times compared to the more conventional implicit schemes, making sewer network simulations more accessible and powerful than ever before. These computational advantages are imperative to effectively and efficiently model very large and complex networks.

“We continue to raise and bar and release new advancements that push the limits of sewer network analysis,” said Paul F. Boulos, Aquanuity Chairman and CEO. “Built for simulation speed, accuracy and stability, the new implicit solver significantly boosts modeling speed and simulation confidence, equipping users with unprecedented capabilities for modeling large and complex sewer systems. We are thrilled to introduce this breakthrough modeling solution to drive our industry innovation forward.”
