I suspect this is an initial value problem and CP is having trouble determining the phase. For the PT inputs, the phase is clearly liquid. Before you call update(), set...

@ibell & @jowr This looks to be related to #1611. Some debugging shows that in ``HelmholtzEOSMixtureBackend::p_phase_determination_pure_or_pseudopure`` when _p is potentially on the saturation curve between ptriple and psat_max (pcrit), the...

Looks like Brent() solver fails (probably because the solution point is at the very end of the ancillary curve) but error is caught and the catch code calls Secant(). There...

This is Pandora's box. In addition to p = pcrit, there are bands above and below pcrit where secant() fails and can't determine phase. The bands move depending on the...

Probably related to #1678 Problems with Brent solver determining phase very near the critical end of the ancillary curves, which is where your pressure is. No solution so far.

I can't do anything aggressively until the 10th.

@drmartinrohde I think everything you need to know is on the CoolProp site under the [Julia Wrapper](http://www.coolprop.org/dev/coolprop/wrappers/Julia/index.html#julia), although it will take a bit to setup the pre-requisites for compiling your...

Hmmm.. I'm not a mac guy. Did you try treating it like the .so file in the instructions? Maybe one of the mac guys can help here.

Please note that at a fixed Enthalpy and variable pressure, you are not at the saturated liquid state for all values of pressure. Also not that the IF97 formulation, while...
