New release - FINE™/Turbo & FINE™/Design3D v11.2

    Yannick Baux     News     07.03.2017

We are glad to announce the Official Release of FINE™/Turbo & FINE™/Design3D version 11.2.

This version comes with a documentation platform accessible on-line, or for download with the software package, in our customer area on AutoBlade™, AutoGrid5™ and CFView™ are also available as stand-­alone.

Several improvements and new capabilities, described in the section 'New features' of the documentation, have been introduced to ease your daily work and extend the scope of application of FINE™/Turbo and FINE™/Design3D, in particular:



FINE™/Agile 11.2

FINE™/Agile is the result of the integration of AutoGrid5™ and FINE™/Turbo into Concepts NREC Agile Engineering Design System. With FINE™/Agile, NUMECA offers a comprehensive turbomachinery solution from preliminary design to 3D CFD detailed analysis.

Designs created in AxCent®, Concepts NREC’s 3D detailed design module, can be analyzed with the NUMECA tools with just the push of a button.






FINE™/Design3D connects to AxCent®

With FINE™/Design 3D 11.2, it is now possible to perform a 3D CFD optimization using AxCent® as the parametric CAD modeler. With AxCent®, you can optimize the exact same geometry right from the preliminary design stage without re-fitting or geometry deviation.

Among many other new capabilities, AxCent® enables the user to perform a multi-stage optimization without additional scripting and adds many parameters related to manufacturability.






AutoGrid5™ - Partial gap defined by a cylinder

AutoGrid5 respects the cylindrical size and shape when defining the partial gap by a cylinder. One example of application is the mesh of a Kaplan turbine blade where whose pivot arm needs to be captured.


FINE™/Turbo - NLH: Injection of user-defined frequencies

In addition to the NLH flexibility, it is now possible to solve any user-defined harmonic not necessarily linked to the blade passing frequency. The user can define an inner perturbation that develops within a row and which can cross a rotor/stator interface, allowing him to model any periodic phenomenon whose frequency and mode is known. One example of application is the modeling of the rotating stall phenomenon.

FINE™/Turbo - NLH speed-up with CPU booster

The NLH method is now compatible with the well-known CPU Booster acceleration technique. With CPU Booster, an NLH computation converges up to 10 times faster!


FINE™/Turbo - Rothalpy imposed boundary condition

It has been reported that the commonly used adiabatic wall could not be a suitable boundary condition for non-rotating shroud in a centrifugal compressor configuration and could lead to the overprediction of the total temperature ratio distribution at the endwall , particularly at the casing in a rotor.

To correct this inaccuracy, FINE™/Turbo introduces a new type of boundary condition based on rothalpy conservation.


HPCC compressor with a 4:1 pressure ratio

The impeller contains 15 main blades and 15 splitter blades, and the diffuser includes 24 vanes.

Design speed is 21,789 rpm with a mass flow rate of 4.54 kg/s.

Adiabatic and rothalpy preserving wall boundary conditions are compared.
