Hello
I am trying to decipher the input files for the two-phase example of a bubble column, in order to be able to modify them for my own application.
I understand all the 'transportPropoerties' info except for "R":

phase1
{
rho 1;
rho0 0;
R 287;
Cp 1007;

nu 1.589e-05;
kappa 2.63e-2;

diameterModel isothermal;
isothermalCoeffs
{
d0 3e-3;
p0 1e5;
}
}


Any ideas?
Thanks!!
