Efficient and reliable CFD

The design and optimization of components exposed to a flow requires a detailed understanding of the prevailing flow conditions. As these depend strongly on the application, Cadence focuses on the development of application-specific software tools for CFD, optimisation, and aeroacoustics.

The fastest and most dedicated CFD solver for turbomachinery

Description

Turbo is the fastest CFD suite for turbomachinery on the market. Compressors, wind turbines, turbochargers, aero-engines, hydraulic turbines and pumps or gas turbines: Turbo is specifically designed for these applications. What makes it so fast? A fully structured approach, multi-grids and acceleration techniques like residual smoothing, the CPU-Booster™ or the NLH method.

Whether the fluid is incompressible or compressible, sub- or supersonic regime – Turbo is your tool. A user-friendly and intuitive graphical interface enables you to setup, organize and post-process the numerical computations of your turbomachine efficiently.

Turbo is fully scriptable and can be accessed via batch mode, making seamless integration and automated simulations of speed lines or entire compressor/turbine maps possible.

Fast all-purpose CFD solver

Description

Open is a simulation suite to compute complex internal and external flows. The range of applications covers turbomachines, vehicle aerodynamics and multi-physics problems like combustion or heat transfer. The extension OpenLabs™ adds a very powerful interface to modify existing or create own physical models, with an easy-to-use meta programming language. In this way, simulation-specific parameters which are usually not accessible in a CFD-code can be adjusted. For instance, you can customize turbulence models, add source terms or build completely new models.

  • HEXPRESS™: automated generation of fully hexahedral grids
  • HEXPRESS™/Hybrid: parallel unstructured hex-dominant mesh generator for most complex and unclean geometries
  • Open solver: multigrid, convergence acceleration, automatic load balancing
  • CFView™: qualitative and quantitative post-processing, fully scriptable
Solving
  • Open

Key Features

  • Rotating and stationary flows, creeping to hypersonic regime
  • All types of fluids (incompressible, perfect or real gas, compressible liquid and condensable)
  • Multigrid convergence acceleration
  • OpenLabs™: enjoy the flexibility of an open-source code – like OpenFOAM – combined with the reliability of a commercial software
  • State-of-the-art methods: LES, DES, DDES
  • Python-API: an efficient interface to automate your workflow

CFD system dedicated to marine applications

Description

Marine is a CFD code designed specifically for multiphase hydrodynamic problems, developed at the Ecole Centrale du Nantes and distributed commercially by Cadence. Marine has quickly become a global player and is chosen worldwide by ship designers and naval architects: from commercial applications up to racing, like the America’s Cup Teams.

Thanks to the C-Wizard, full CFD setups (including the meshing) for typical applications like resistance, planing hulls, propulsion, seakeeping and maneuvering are prepared in a few clicks. Marine is fully scriptable and ready for even the most complex marine and offshore problems, thanks to overset grids, dynamic libraries and adaptive grid refinement.
