### Description When using Peng-Robinson for mixtures, adding the binary interaction parametes can lead to faulty calculation results for the phase envelope and two-phase calculations (and probably liquid calculations as...

Add fluid_param_string and get_JSONstring to cubic backend

1

### Description of the Change fluid_param_string and get_JSONstring were added to the cubic backend. Implementation is comparable to HelmholtzEOSMixturebackend See PR #1371. Minor changes to CubicBackend.cpp were made: - If...

AbstractState Mathematica Wrapper

### Description of the Change [ *We must be able to understand the design of your change from this description. If we can't get a good idea of what the...

Add volume translated density parameters

1

### Description It would be handy to calculate and have access to volume translated densities in cubic backends. Since modifying the actual density messes with calculation of all other properties...

Fix HEOS fugacity for mixtures in the two-phase region

3

### Description of the Change I noticed that when calculating the fugacity for mixtures in Peng-Robinson EoS the results did not quite made sense. Since the fugacity of a component...

Wrong enthalpy outputs for illegal quality inputs

2

### Description When updating an AbstractState within the two-phase region with illegal quality inputs (1), the update function will throw an error but outputs will still be generated. ### Steps...
