Using IVC Calculator to find the species mass fractions in homogenous mixture

  Dear Sir,
  
  I hope this message finds you well.
  
  Can you please let me know how the IVC mixture in tutorial 2 (Dual fuel combustion modelling using a 60% sector mesh) of Forte was calculated? I followed the reference paper (Referenced at the end of tutorial 2) and used the given values in the IVC calculator:
  
  mass of gasoline = 104.96mg
  
  mass of diesel = 23.04mg
  
  Phi = 0.77
  
  EGR = 0.455
  
  However, I did not get the same values which are provided in the dual fuel tutorial. Can you please let me know how we can use the IVC calculator to find the mass fractions of species in a homogenous mixture of gases at IVC when gaseous fuel is premixed with the air and liquid fuel is injected directly into the cylinder?
  
  Many thanks!

  The IVC values provided in the tutorial are most likely copied from the referenced paper for the multicomponent gasoline surrogate, not calculated using the 1-component gasoline surrogate.
