Release History

Version Description Comments
 
Release history
 
5.7.0
  NEW Tyre model import from Pacejka coefficients

5.6.4
  Rebuild to fix problem with Help files  
 
5.6.0-5.6.3
  This is a major upgrade that improves many aspects of the simulation especially in corner speed solving Lap times will change.

  FIX Use of on-disk rather than in-memory bump rubbers for bump rubber gap display  
  FIX Units issues:
- mass units not being written to units.dat
- pressure and temperature units being reset when opening event with no units.dat file
- not recognising "in H2O" or "in Hg" pressure units

  FIX UI bug in track segment diagnostic display (displayed CzF values for CzR/Cx)  
 
5.4.4-5.4.5
  FIX Inventory ARB value was always 0 when torsional rate required All ARB rates now torsional not linear, before linear was used when Fixed Values used for Suspension
  FIX Rack Ratio was only correct when displacement units were mm  
  CHANGE AppReleaseDate now 2012.06.01  
 
5.4.4
  FIX Inventory ARB value was always 0 when torsional rate required Worked OK when linear rate required
 
5.4.3
