ClapeyronThermo/Clapeyron.jl: v0.6.21

Published February 7, 2026 | Version v0.6.21

Software Open

Clapeyron v0.6.21

Python: official python wrapper, available in pypi: pyclapeyron.
GroupParam can now store non-integer values.
MultiPhaseTPFlash: support for Gamma-Phi models
Cubics: translation now does not allocate in most cases.
New model: translated industrial PC-SAFT (iPCSAFT)
New model: VTPR with temperature-dependent translation (TVTPR)
Electrolyte models: mean_ionic_activity_coefficient and osmotic_coefficient (and their saturated variants), can now be called directly without specifying salts, if the model forms binary salts. For example, (osmotic_coefficient(model,p,T,m)) is equivalent to(osmotic_coefficient(model,salts,p,T,m)), where salts = Clapeyron.auto_binary_salts(model)
DHModel: improved numerical stability of a_dh when the electrolyte concentrations are small.
association options can now be initialized directly from a symbol: (PCSAFT(["water","ethanol"],assoc_options = :cr1))

AntoineSaturation now uses SI units
Fixes in PenelouxTranslation (inverted parameters for PR and RK models)
Patel-Teja: the correlation for ζc is used first instead of the experimental critical volume
Various documentation improvements
Fixed precompilation errors in ClapeyronSymbolicsExt
