 Multi-Physics Simulation

  • Ideal for incompressible/”weakly compressible” multiphase flows
  • Cryogenic fluid modeling capability
  • Advanced cavitation models that account for thermal/evaporative cooling effects on liquid
  • 6-DOF dynamic body motion
  • Robust tools for modeling rotating turbomachinery, including mixing plane and frozen rotor (steady), as well as sliding interfaces (unsteady).

  • All-speed flow solver for compressible fluid mixtures
  • Non-ideal, real fluid EOS for gas/liquid mixtures that can model near-critical flows and adiabatic compression of liquid.
  • Chemistry manager for specifying species and reactions in Chemkin/Cantera formats
  • Advanced features for reacting flows including stiff chemistry solver, ISAT, and laminar flamelet model.
  • 6-DOF dynamic body motion
  • Robust tools for modeling rotating turbomachinery, including mixing plane and frozen rotor (steady), as well as sliding interfaces (unsteady).

  • 3D heat conduction solver
  • Generalized fluid-thermal boundary conditions for parallel computing of coupled solid-fluid domains.

Pre and Post-Processing Utilities

CRUNCH CFD® comes with PRECRUNCH and POSTCRUNCH. Our preprocessing utility supports multiple mesh file formats. Our postprocessing utility can export to multiple solution formats.

User-Friendly GUI

The CRUNCH graphical user interface streamlines the setup process. Versions for Windows, Linux, and MacOS are all available.

Computing Platforms

Available for cloud computing on Amazon EC2 with preloaded images. Also available for LINUX systems with MPICH2 and OpenMP libarries for parallel computation.

CRUNCH CFD® is a multi-physics simulation tool for analyzing complex flow problems in a modular framework, with specialized fluid and thermal solvers. CRUNCH CFD® features an advanced multiphase formulation with generalized non-ideal equations of state, unsteady hybrid LES/RANS models, far-field acoustic propagation modules, and advanced chemistry tools for modeling reacting flows. In addition, moving body problems are solved with a combination of grid deformation with localized grid remeshing. CRUNCH CFD® is also highly scalable for large-scale computing.
