Analysis Summary

This page reports the analysis of the geometry analysis using One-Click CFD.
The analysis setup uses the following input parameters:

  • Speed: 44.7 m/s

The uploaded geometry has the following characteristics – please check these carefully.
Mistakes can easily happen particularly when using unit-free format such as STL.

  • Length (y axis direction): 5.00 m (Y from -1.00 to 4.00 m)
  • Width (x axis direction): 2.01 m (X from -1.01 to 1.01 m)
  • Height (z axis direction): 1.06 m (Z from -0.05 to 1.01 m)
  • Frontal area – A: 1.74 m2. This is the projected area of the vehicle in the y axis direction.

The analysis was undertaken for the full car.

    Downforce distribution

The drag and downforce distribution graphs shows the distribution of the drag and downforce surface alongside the car body. The distribution is obtained by integrating the pressure induced forces at sections of the car. The integral of the drag and downforce is equal to the total pressure induced drag and downforce.
These graphs excels at providing information on where high drag and downforce are generated. It can also be used to identify inbalance in downforce distribution, such as does the rear wings generates significantly higher downforce than the front wings.
