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.
- Be
tter 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™.
