Documentation | Install instructions

The IDAES PSE framework addresses the capability gap between state-of-the-art simulation packages and general algebraic modeling languages (AMLs) by integrating an extensible, equation-oriented process model library within the open-source, DOE-funded, Pyomo AML, which addresses challenges in formulating, manipulating, and solving large, complex, structured optimization problems.

Patch release:

• Improvements to Tutorials
