Unsupported model type for methanol

[Matthew-Boyd]

Modeling methanol with the multifluid EOS causes the error:

Bad type:ResidualHelmholtzAssociating; allowed types are: {ResidualHelmholtzPower,ResidualHelmholtzGaussian,ResidualHelmholtzNonAnalytic,ResidualHelmholtzGaoB,ResidualHelmholtzLemmon2005,ResidualHelmholtzExponential,ResidualHelmholtzDoubleExponential,ResidualHelmholtzGenericCubic,ResidualHelmholtzPCSAFTGrossSadowski2001}

I'm assuming you are using a CoolProp fluid file. The default fluid files for CoolProp (those used by default in teqp) use the associating fluid terms that were developed for methanol and acetic acid. I would recommend to use the file converted with the routines in REFPROP-interop as exposed like this: https://teqp.readthedocs.io/en/latest/models/REFPROP_conversion.html

I'm using teqp::cppinterface::make_model() with the JSON data from the default teqp JSON fluid file.

How do you best model methanol in teqp using its CoolProp fluid file, or must the converted FLD file be used instead?

The converted fluid file must be used. On my CoolProp development list is to match the EOS used in REFPROP for methanol as the associating one has issues
