Question about rhoCentralFoam
 
In rhoCentralFoam, you are interpolating rho, rPsi, and e to the faces.
  1. What is rPsi ? It seems like it is R*T where R = gas constant. Is this correct.
  2. e is the internal enernal. This depends on rho and rPsi through the equation of state. So why interpolate e separately when rho and rPsi are already available at the faces ?
