IDAES-PSE 2.5.0 Release Highlights
Upcoming Changes
- IDAES will be switching to the new Pyomo solver interface in the next release. Whilst this will hopefully be a smooth transition for most users, there are a few important changes to be aware of.
- The new solver interface uses a different version of the IPOPT writer (“ipopt_v2”) and thus any custom configuration options you might have set for IPOPT will not carry over and will need to be reset.
- By default, the new Pyomo linear presolver will be activated with ipopt_v2. Whilst are working to identify any bugs in the presolver, it is possible that some edge cases will remain.
- IDAES will begin deploying a new set of scaling tools and APIs over the next few releases that make use of the new solver writers.
- The old scaling tools and APIs will remain for backward compatibility but will begin to be deprecated.
New Models, Tools and Features
- New diagnostics check for near-parallel variables and constraints.
- New diagnostics tools for identifying causes of infeasibility in models.
- New example for creating a custom model of a liquid-liquid extractor unit operation.
Bug Fixes
- Fixed bug in Gibbs reactor that caused it to appear to have additional spurious degrees of freedom.
- Fixed bug in the Modular Property Framework that would cause errors when trying to use phase-based material balances with phase equilibria.
- Fixed bug in Modular Properties Framework that caused errors when initializing models with non-vapor-liquid phase equilibria.
Testing and Robustness
- Deployed the IDAES Diagnostics Toolbox to confirm that there are no structural or numerical issues in the core model libraries.
- Additional robustness tests for core model, and some associated improvements in the converge tester class.
- Fixed a number of issues that were causing unexpected warnings to be emitted during testing.
Deprecations and Removals
Removed examples for RIPE tool which has not been supported for a number of releases.
What's Changed
- Add constraint to exclude TensorFlow 2.16.1 and above by @lbianchi-lbl in #1373

native_types
andpyomo_constant_types

IDAES-PSE 2.4.0 Release Highlights
Deprecations
- Convergence Analysis tool (idaes/core/util/convergence): deprecated in favor of new Parameter Sweep tools. To be removed in v3.0.0.
New Beta Capabilities
- Parameter Sweep Tool (
idaes.core.util.parameter_sweep
)- A new API for defining and performing parameter sweep studies on IDAES models has been developed
- Diagnostics Tools (
idaes.core.util.model_diagnostics
)- New methods for identifying duplicate variables and constraints have been added to the diagnostics toolbox
- New tools for detecting ill conditioning in Jacobians have been developed and are available in the model_diagnostics module. These provide alternatives to the existing DegeneracyHunter toolbox, and will eventually be merged with this capability, but initial working versions have been provided as beta capabilities for interested users
IpoptConvergenceAnalysis
(replaces deprecated Convergence Analysis tool):- A new tool for performing convergence analysis studies that leverages the new Parameter Sweep tools has been developed. This tool allows users to define the input parameters to their model and sampling methods for these (leveraging Pysmo's sampling tools) and to then solve their model across the sampled domains and return a summary of the solver performance (IPOPT only)
Improved Models
- Thickener model (
idaes.models.unit_models.solid_liquid.thickener
)- Improved model to include predictive correlations for unit sizing based on settling velocity measurements (steady-state only)
- Modular Property Packages
- Added general support for calculating critical properties of mixtures using defined Equation of State modules. New API defined for Equation of State modules in order to define the necessary constraints for calculating critical properties (most EoS modules DO NOT support calculation of critical properties (yet))
- Added new methods to Cubic Equation of State module to support calculation of critical properties

Improvements and bug fixes
- Fixed oversight which precluded using
Mixer
andSeparator
models when inherent reactions were present in property package - Added reporting methods to the
