What's New in the Latest Release of Cadence Fidelity CFD

    Anne-Marie Schelkens     News     23.06.2022

Cadence releases Fidelity CFD version 2022.1, with many new features to speed up and streamline your workflow for highly accurate performance simulation of multiphysics systems.

New User Interface Focused on Ease-Of-Use

The user interface changed to match the Cadence brand experience. Beyond the aesthetical changes, the user experience has been reviewed to ensure a consistent and user-friendly workflow from geometry creation to the analysis of results. 

All tools have been moved to a new toolbar that adapts to each context. The new field selector allows the user to select the evaluable or computed fields based on the setup.

Simplified Structured Mesh Generation

It is now even easier to generate high-quality multiblock structured meshes for turbomachinery, thanks to:

  • Automatic leading and trailing edges wizards
  • Definition of gap and fillet from curves
  • Automatic bulb detection
  • Simplified blade-to-blade grid distribution
  • and the refactoring of Python functions

Unstructured Mesh Generation Made Faster and More Flexible

New tools now check the geometry before unstructured mesh generation. The volume-to-surface approach is ported to multi-node mesh generation to utilize all available computing resources. Pointwise technology improves the surface-to-volume approach with anisotropic refinement at leading and trailing edges and extrusion of boundary layers.

Greater Flexibility and Interoperability Facilitate the Migration

New file formats are now supported, among which are the Tau, CGNS 64-bit, and IGG formats. And it is possible to hook Python scripts to the different tasks (geometry import, mesh generation, simulation, etc.) to automatize or customize the workflows.

More Models for Increased Accuracy

The support of multiple reference frames enables the simulation of rotating car wheels or multicopter drones for example.

New turbulence models have been implemented such as the RSM model for the simulation of water turbines or the DES model for the simulation of car aerodynamics.

A new flux-balance non-reflecting rotor-stator interface increases the accuracy of high-speed turbomachinery simulations.
