The newest verion of FINE™/Open with OpenLabs™ has just been released! The main focus of this new release is on Robustness, Flexibility and Stability of our unstructured flowsolver.

 

Highlights

HEXPRESS™: Store the hub and shroud curves

When a structured AutoGrid5™ project is imported into HEXPRESS™, the hub and shroud curves definition is stored in the mesh file to compute the span and stream positions within CFView™.

 

 

 

 

 

HEXPRESS™: Define rotor/stator interface with zero radius

The rotor/stator interface can now include regions where R=0.

 

 

 

 

 

HEXPRESS™/Hybrid: Better viscous layers inflation

Several improvements have been made to better inflate viscous layers, among which:

• Less compressed and deformed Euler mesh.

 

 

 

 

• Stretching ratio is better respected when closing viscous layers.

 

 

 

 

• Better global inflation by respecting the total VL thickness.

 

 

 

 

• Inflation steps will succeed more consistently.

 

FINE™/Open: Flow solver robustness improvements

Our experts have used a large database of industrial test cases to ensure maximum robustness of your simulations with the default set-up parameters.

Here are a few examples of changes:

• The CFL number used during the FMG can now be set independently from the general CFL number for each block. Its default value has been updated.
• Deactivation of the residual smoothing during the FMG.
• Use of the central scalar dissipation scheme during the FMG when the central matrix dissipation scheme is selected.

We also have implemented a new solver for solid blocks based on the Conjugate Gradient (CG) method, which is less sensitive to the mesh quality and is unconditionally stable. 

 

                

 

FINE™/Open: Flexibility for the multi-rank harmonic method

Similarly to FINE™/Turbo, users have now more flexibility to set up their multi-rank harmonic computation. 

In particular, the new implementation enables to:

• define different numbers of harmonics of rank 1 and rank 2.
• manually select the harmonics that will be solved during the simulation.
• restrict the clocking effects to time average solution (only for rank 2 computation).

 

 

 

 

 

 

 

FINE™/Open with OpenLabs™: Variable rotation speed and variable timestep

The user can now vary the rotation speed for steady and unsteady simulations, and the physical time step for time accurate computations through OpenLabs™.
