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
