VECTIS is a three-dimensional fluid dynamics program that has been developed specifically to address fluid flow simulations in the vehicle and engine industries. VECTIS is developed around a completely automatic mesh generator, providing a rapid turnaround time for CFD analyses. The fully automatic mesh generator, unique to VECTIS, provides a distinct advantage over most other commercial CFD tools; in that it ensures CFD is an integral part of modern engineering development programmes.

Applications

  • In-cylinder air motion and mixture preparation
  • Spray dynamics
  • Combustion modelling
  • Intake system component design and optimisation
  • Exhaust system component development, exhaust gas recirculation, catalyst optimisation and exhaust muffler development
  • Coupled 1D/3D simulations for more accurate transient results
  • Coolant circuit design and development
  • Advanced thermal management using conjugate heat transfer, radiation and transient simulations allows hot soak, thermal shock and warm-up simulations
  • Vehicle thermal management simulations
