Description

It would be useful to expose

  • USE_MAXWELL_TABLE to get the maxwell constructed table if available
  • EOS_SPLIT_COWAN to turn on Cowan splitting explicitly for electron/ion splitting if needed
  • EOS_CALC_FREE_ENERGY to get a free energy if it's unavailable even if it's less good than a first-principles version

Contributor guide

Research direction
Study the existing sesame2spiner function to understand how options are currently exposed. Find the relevant source files and add the three new constants USE MAXWELL TABLE, EOS SPLIT COWAN, and EOS CALC FREE ENERGY as new options, ensuring they are properly defined and passed through the function.
