3.5.0-beta.4

Testing ARM builds

3.5.0-beta.3

This is a partial pre-release for integration testing purposes. This release contains ARM binaries for MacOS, el8, and Ubuntu. These binaries are not compiled with HSL. Compared to https://github.com/IDAES/idaes-ext/releases/tag/3.5.0-beta.1, these binaries contain a workaround for a Mumps-Metis incompatibility.

v.3.5.0-beta.2

This is a Python 3.10 partial release created for integration test purposes and is not meant for general use. Binaries for Mac (darwin) and aarch64 are not included in this release and will be added in a subsequent pre-release.

v3.5.0-beta.1

This is a partial pre-release for integration testing purposes. This release contains ARM binaries for MacOS, el8, and Ubuntu. These binaries are not compiled with HSL. The binaries were compiled using the scripts (and --without-hsl option) in the branch: https://github.com/Robbybp/idaes-ext/tree/without-hsl.

3.5.0 Beta

This is a partial release created for integration test purposes and is not meant for general use. Binaries for Mac (darwin) and aarch64 are not included in this release and will be added in a subsequent pre-release.

3.4.0 Release

The following changes were made since the previous release:

• A function was added to calculate x/(exp(x) - 1), which deals with x = 0, by using a Taylor series expansion near x = 0.
• Isothermal compressibility and fugacity coefficient functions were added to the Helmholtz EoS functions
• PETSc (https://petsc.org/release/) was updated to 3.19.2

3.3.0 Release

This release adds more property functions to the general Helmholtz equation of state functions.

3.2.0 Release

This release adds Helmholtz equation of state external functions for properties as a function of (h, p), (s, p), and (u, p), allowing properties to be more directly calculated without composite function calls.

3.1.0

Changes:

1. The old IAPWS95 and Span-Wagner CO2 external functions were removed in favor of the new general Helmholtz EoS.
2. The general Helmholtz EoS now uses data files to define parameters and expressions for components. Components can be added without recompiling the binaries.
3. PETSc was moved to version 3.18.1 for all platforms except RHEL7 where it remains at 3.17.1.

3.0.0 Release

This release adds a new general Helmholtz equation of state external function package and provides headers required to build against the Ipopt shared library. There is also a bug fix for a missing derivative in the IAPWS95 and Span-Wagner property functions
