pyKO CHANGELOG

v0.6.x-dev 2023-07-05 in progress

Added constant heat capacity temperature to Mie-Grueneisen EOS; initialize positive temperature with zero internal energy
Added constant heat capacity temperature to Tillotson; initialize positive temperature with zero internal energy
Now initial temperature and heat capacity are required inputs for TIL and MGR EOS
Added functions to calculate the cold curves in MGR and TIL classes
Fixed bugs in iSALE function for Tillotson EOS; now Hosono, iSALE, and Asphaug versions of Tillotson agree
Added sound speed calculation to Mie-Grueneisen EOS; only used for time step calcs and output; artificial viscosity calculation is unchanged.
Removed s2 input for MGR EOS; Wilkins implementation of MGR assumes linear Us=c+s*up and gamma/volume=constant
-- Wish list: option for non-linear Us, non-constant gamma/volume MGR in future
See Test13 and Test14 jupyter notebooks for these updates and EOS function checks
Updated some comments/units
Changed IDG input key gamma0 to gamma.

Geometries
- Planar, cylindrical, or spherical
Boundary conditions
- Fixed: symmetric, zero particle velocity
- Free: zero pressure
Elastic-plastic model
- Von Mises
Interfaces
- Initial gaps
- Dynamic fracture
- Void closure on contact
Gravitational acceleration
- Initialization of isothermal layers only
Equations of state
- Ideal gas
- Mie-Grüneisen
- Tillotson (needs more testing)
- Tabular/SESAME, with tools for tabulated ANEOS; interpolation schemes are currently very simple
Input and output
- For testing and comparison to fortran KO:
  Fixed formatting ascii input and output files
- Preferred I/O:
  Yaml configuration (input) files with unit conversion using pint
  Binary output files using pickle with units
- Customizable outputs:
  User-defined cell data output in binary format
  Debug output in binary format with all node variables

Fortran-style input files are deprecated for the yaml input file format. Not backwards compatible to earlier stages of development.
