CFturbo 2026 R2.2 Build 135 Suite Win x64

Software Overview

---

CFturbo provides an integrated environment for turbomachinery conceptual and detailed design. Its interactive workflow supports the creation and variation of complex flow-path geometries, including impellers, stators, and volutes. Engineers can use built-in approximation functions and semiautomatic design proposals to accelerate development while retaining control over important design parameters.
The suite also includes CFturbo FEA for structural analysis and CFturbo BLADERUNNER for automating turbomachinery CFD workflows. CFturbo FEA provides a graphical interface for CalculiX-based simulations, while BLADERUNNER automates selected simulation and performance evaluation tasks using compatible external CFD software.

The release dated September 18, 2026, includes crash fixes, graphical performance improvements, usability refinements, export adjustments, and an additional meridional leading-edge feature.

• Mean Lines Stability: Fixed a crash affecting wrap-angle changes in certain special cases.
• Performance Prediction: Fixed an issue that could cause a crash when opening the performance prediction dialog with references under specific conditions.
• 2D Graphics Performance: Improved behavior related to panning and zooming in the Meridional Contour dialog design diagram.
• Export Reliability: Fixed an issue where the export process could abort immediately after an earlier aborted attempt.
• Live Updates: Addressed missing live updates of beta progression in Mean Lines.
• Uninstallation: Corrected the use of a nonexistent file during software removal.
• Simerics Export: Updated the export behavior to declare gravity as a constant in the SPRO file.
• View Units: Corrected the unit type for the additional t, m view in Mean Lines.
• Monitor Detection: Improved monitor-size checking in the main form.
• Meridional Contour Hint: Refined the splitter leading-edge hint for greater specificity.
• Axial Impeller Feature: Added initial behavior that makes the splitter's meridional leading edge identical to that of the main blade.

CFturbo FEA and BLADERUNNER

---

CFturbo FEA provides a graphical environment for structural strength simulation using CalculiX. Its capabilities include static stress and deformation calculations, along with modal analysis for supported 3D geometries.
CFturbo BLADERUNNER is designed to automate workflows for turbomachinery CFD projects. It can run supported simulations for CFturbo models, calculate performance curves and maps, and compare simulation results across different geometries.
Important: BLADERUNNER does not include its own CFD solver. The supplied release information identifies CFturbo SMP (Simerics MP) as the supported external CFD software, which must be installed separately. CFturbo BladeModeler also requires Simerics MP/MP+ to be pre-installed.
