The 2025.2 release is focused on speed, automation, and manufacturing readiness for turbomachinery design.
Faster Optimization: Instantly re-run the Reactive Response Surface (RRS) surrogate model for new optimization objectives/constraints without repeating costly CFD simulations.
Maximum Automation: Introduced a new Python API for scripted control over all TURBOdesign1 settings, enabling greater flexibility and integration into custom workflows.
Expanded CAE: Added support for Cadence FineTurbo and ANSYS Fluent integration, alongside new full-stage analysis workflows (Rotor + Volute).
Production-Ready: Includes a new feature to generate flank millable geometry using user-specified tool paths, ensuring manufacturability upfront.
New Applications: Enhanced concept prediction tools (TD-Pre) with new design modules for waste-water pumps and mixed-flow fans.
The new release of TURBOdesign Suite brings a set of wide-ranging and application specific improvements to enable designers to swiftly create, assess, and improve turbomachinery stages, and to run the design workflow with more automatization, efficiency and clarity.
TURBOdesign Suite integrates end-to-end concept, meanline design, 3D design, volutes and other additional stage components and preparation for manufacture
With a relentless focus on advancing the Machine Learning capabilities of turbomachinery design and optimization, v2025.2 introduces accelerated design exploration, allowing instant re-runs of the Reactive Response Surface (RRS) surrogate model, but for different objectives and constraints from the original generation.
This allows engineers to rapidly explore the design space from a new perspective and instantly evaluate performance trade-offs whilst avoiding the need for any costly CFD re-runs. We have also improved the calculation of ranges for optimizer input variables so that users can more rapidly set up studies with suitable min and max parameter values - ensuring a more efficient design space search. This latest update also supports single phase, two-phase flow and multi-phase analysis as part of the Machine Learning algorithm.
TURBOdesign1 v2025.2 includes new and faster ways to evaluate multi-objective, multi-point optimization studies
A major enhancement comes in the introduction of a Python Application Programming Interface (API) which allows more flexibility, scale and integration for design systems.
The API enables Python scripts to read and write case files, send and get variables, execute the TD1 solver, organise and interrogate data, and create and export geometry. This new aspect of TURBOdesign1 will bring endless adaptability, control, and customization whilst tapping into the power and insight of 3D Inverse Design. The API is backed by comprehensive in-line documentation, and can be run in a virtual environment, in the pre-configured environment provided with the installation, or as an installation to existing in-house Python eco-systems.
TURBOdesign1 v2025.2 includes new and faster ways to evaluate multi-objective, multi-point optimization studies
We have harmonized the behaviour of the existing scripting language used in TD1Script to the actions of the TURBOdesign1 GUI, this allows any User Defined Parameters (UDP) used in either method to be consistent when using either GUI or Script modes. In a further improvement to accessing data from TURBOdesign1, parameters upstream and downstream of the blade passage are identified and accessible.
A major step forward is the arrival of full stage analysis within the CAE integration function of TURBOdesign1. This allows rotor+volute assemblies to be constructed for CFD analysis at the click of a mouse button. TD1 handles all the meshing, domain interfacing, management of boundary conditions and solver control plus the data management from as many opening points as you care to set up. This feature is currently available for centrifugal pumps and compressors and also extends into the optimization capability, so that ‘stage performance’, and volute loss-coefficients are now truly accounting for the volute, and can be used as an optimization objective or constraint.
TURBOdesign1 integrates with numerous 3rd party CAE packages
TURBOdesign1 creates Rotor+Volute analysis in different mesh/solver configurations
We continue to add more compatibility for 3rd party analysis codes to enable integration with the widest possible number of in-house design systems. The 2025.2 release sees the inclusion of Cadence Fine Turbo and ANSYS Fluent as supported high-fidelity analysis options. This means our ‘one-click’ set-up for a CFD simulation initiated from TURBOdesign1 can be directed to the solver of your choice by the simple means of selecting the chosen solver from a pull-down menu. Additionally, user-defined templates can be enabled for both solving and meshing - meaning that the in-house analysis conventions or best-practice are maintained during the CFD runs launched from TURBOdesign1.
In our meanline design and sizing tool - TD-Pre - we have created a new module for the design of waste-water pumps, which includes the ability to specify the maximum solid pass-though size required - which is key to avoiding clogging issues. The module for mixed-flow fan designs is also extended to account for straight-line passages with impeller plus diffuser. The loss modelling for centrifugal compressors with vaned diffuser has been improved so that the inverse design predictions more closely match the performance seen in CFD results.
TURBOdesign-Pre v2025.2 contains a new design module specifically for waste-water pumps
In response to user requests, TURBOdesign Volute now has the ability to define the volute tongue radius, which is important for rotor vibration and pressure pulsation control.
TURBOdesign-Volute v2025.2 contains a control for the position of the volute tongue
In conclusion, this release is built on thoughtful feedback from our customers, and our ongoing commitment to making complex turbomachinery engineering simpler and more productive. TURBOdesign Suite 2025.2 blends powerful optimization with hands-on manufacturing features, supporting engineers every step of the way—from first ideas to the final product.
