Advection for Neutrals

[robfleur]

Before this change, all neutral species were advected (calculations for neutral friction were made considering ALL species). Now, when calculating neutral friction, only advected species will be calculated. Also, there is now a planet file option in aether.json (although the default is already specified as earth.in in defaults.json).

Type of change

• New feature (non-breaking change that adds functionality)

How Has This Been Tested?

There is a script in tests/advect. It runs with no species advected, one species advected (N2), and all specified species advected.

Test configuration

• Operating system: MacOS Ventura 13.1
• Compiler, version number: Apple clang version 14.0.0 (clang-1400.0.29.202)
