WHITE RIVER JUNCTION, VT, May 5, 2026 – Concepts NREC released version 2026.1 of its Agile Engineering Design System (AEDS) to connect turbomachinery design, CFD analysis, optimization and machining workflows. The update adds secondary flow analysis for radial and axial machines, automated data transfer between modules, and new MAX-PAC toolpaths for complex blade geometries.
Expanded Secondary Flow Analysis Capabilities
The latest release extends secondary leakage path capabilities introduced in version 2025.2. Version 2026.1 adds CFD functions for radial and axial machines, including secondary passages with standard, stepped or custom labyrinth seal designs using Cadence Fidelity Fine Turbo and Concepts NREC’s pbCFD. Concepts NREC also updated secondary flow path geometry handling in AxCent to support customization and improve CFD solve success rates.
Reduced Workflow Friction Across Tools
Concepts NREC added module connections to reduce manual setup in analysis. A new automated link between AxCent and CTAADS transfers blade geometry and CFD results into turbine analysis projects. The company also updated the integration between TurboOpt II, and Ansys optiSLang. The connection exchanges inputs and outputs automatically between the two applications during project setup.
Increased Toolpath Performance & Flexibility
The MAX-PAC release adds machining options for complex blade geometries. The update covers roughing, finishing and multi-orientation operations.
New toolpath methods include spiral roughing for single blades in shrouded or tailstock-supported parts when blade-tip entry is not possible. Concepts NREC also added undercutting support for 3+2 roughing operations with lollipop tools, disc cutters and barrel tools. The change increases material removal in each tool orientation and reduces repositioning. Blade finishing toolpaths can extend through the fillet and onto the hub to eliminate cusps and mismatches at the leading edge.
Customized Process Documentation
A new interface in the Machining Setup Properties menu brings process documentation settings into one location. Users can control setup images, column configuration and output format (HTML or TXT) for documentation.
“The pace of innovation in turbomachinery is accelerating and engineers are expected to meet demands, faster than ever before,” said Jonathan Bicknell, VP of software products at Concepts NREC. “This release reflects our ongoing commitment to delivering the most connected and capable environment for engineers, from early design through analysis, optimization, and final machining, so they can focus on solving hard problems with robust tools.”
