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

[Matthew-Boyd]

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?

[ibell]

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

[ibell]

I have converted the Methanol EOS in use in CoolProp to be the same one that is in REFPROP. The interop script might need to be updated to match.

I bumped the EOS in CoolProp for methanol back to what is used in REFPROP; I suppose we can now grab the CoolProp JSON for methanol and backport that to teqp. Do you want to do that or shall I?
