Description

Write reaction driven porosity as a function of the plated & SEI thicknesses for lithium-ion models (lead-acid stays the same).

Fixes #1505

Type of change

Please add a line in the relevant section of CHANGELOG.md to document the change (include PR #) - note reverse order of PR #s. If necessary, also add to the list of breaking changes.

  • Bug fix (non-breaking change which fixes an issue)

Key checklist:

  • No style issues: $ flake8
  • All tests pass: $ python run-tests.py --unit
  • The documentation builds: $ cd docs and then $ make clean; make html

You can run all three at once, using $ python run-tests.py --quick.

Further checks:

  • Code is commented, particularly in hard-to-understand areas
  • Tests added that prove fix is effective or that feature works

Had to add the rest periods and reduce the sampling period at discharge, otherwise simulations didn't converge.

I commented it out as it is not used. Should I delete it? Because it is checking the options rather than the submodels at the moment there is no way we can enter these if statements.

Thanks @brosaplanella ! Just remove the commented out lines then we can merge
