Hi All,

I was computing a phase diagram using Winprop but I am not getting any bubble point curve.
I checked the compositions and have C1-C4 as 79 % and selected PR (1978) as the EOS.
I have regressed on CCE and CVD data and am getting a fairly good match on CCE.

Is the cubic equation of state not getting solved properly to get a proper critical point as the root ?
