liquid properties: pv() member function
 

Dear all,

Does anyone know what is the difference between this two pv() member functions that is called from setRelaxationTime.C. (1.6 version)

1) pressureAtSurface = fuels.pv(pressure, T(), X())

2) psat[i] = fuels.properties()[i].pv(pressure, temperature);

I know that the first pv() is defined in the liquid libraries but I'm not sure where the latter pv() is defined.

Best,
Fairus
