Performance Mapping

TotalSim has the ability to map the aerodynamic performance of vehicles over a range of:

  • Ride heights (including roll, pitch, steer and yaw)
  • Speeds
  • Wing angles
  • Gurney heights

TotalSim’s bespoke performance mapping tools are quick to setup, fully automated and allow for rapid turnaround
of CFD results. Performance mapping tools are designed to manipulate the pre-processed CFD model without the need for complicated and time consuming CAD model updates.

In particular, TotalSim has developed a sophisticated ‘Ride Height Changer’ tool which can automatically update the geometry of the CFD model based on a given ride height setting. ‘Rider Height Changer’ applies kinematic translations and rotations on suspension and wheel components to accurately represent the orientation of the real life vehicle undergoing roll, pitch or yaw. ‘Rider Height Changer’ is highly flexible, allowing the user to specify front and rear ride-heights, roll, yaw, and steer. This can all be automated for a number of flow conditions.
