For detailed instructions on how to get started using the Framework, as well as examples, tutorials and references, take a look at our online documentation.

Highlights for this release are:

• Updates to be compliant with Pyomo 6
• New get_solver tool for creating solver objects which supports definition of default solvers and options
• Improved handling of solver options during initialization
• Additional properties in Generic Property framework, including multiple flow bases, internal energy, and constant volume heat capacity.
• New Generic Property module for constant pure component properties
• Extension of core framework to support aqueous solutions of ions, including support for true and apparent species compositions
• Performance curves in isentropic pressure changers
• New utility functions for accessing scaled and unscaled Jacobians and problem condition number
• Support for automatic scaling tools in Generic Property and Reaction packages
• Numerous improvements to automatic scaling functions
• Improved output of stream tables for cases of multiple property packages with different state variables
• Fixed bug in some property packages where enthalpy density was used instead of internal energy density in energy balances
• Fixed underlying bug preventing cloning of models, which was necessary for GDP problems
