Overview

Q

Qatium

Qatium provides you with a simple, browser-based digital twin of your water network. By uploading your existing GIS and hydraulic data, you can create a live model that helps you visualize how water moves through your system. You can simulate real-world scenarios like pipe bursts, pump failures, or fire flow demands without affecting your actual infrastructure.

The platform is designed for water utilities of all sizes, from small rural districts to large municipal operators. You can use it to identify leaks, optimize pressure zones, and plan maintenance schedules more effectively. Because it runs in the cloud, you can collaborate with your entire team and external consultants in real-time using a single source of truth for your network data.

SimFlow

SimFlow is a powerful computational fluid dynamics (CFD) platform that brings the capabilities of OpenFOAM to a user-friendly graphical interface. You can handle complex engineering challenges including compressible and incompressible flows, heat transfer, and chemical reactions without writing code. It allows you to import geometry directly from CAD software, create high-quality meshes, and monitor simulations in real-time to ensure accuracy and efficiency.

Whether you are designing automotive components or optimizing HVAC systems, the platform provides the tools to visualize flow patterns and pressure distributions effectively. You can run simulations on your local machine or scale up to high-performance computing clusters for massive datasets. It is designed for engineering professionals and researchers who need the precision of open-source solvers combined with the speed of a modern, intuitive workflow.
