| - Add (optional) smooth approximations for the `minimum`, `maximum`, `Heaviside`, and `AbsoluteValue` operators ([#1223](https://github.com/pybamm-team/PyBaMM/pull/1223)) |
There was a problem hiding this comment.
Very minor thing: should minimum and maximum be capitalised or is it because the smooth approximation is for the method but not for the class?

Description
Add smooth versions of the heaviside, minimum, and maximum operators, which can all have discontinuous values and/or derivatives. This clearly improves the performance of the solver, when applicable. A new setting
min_max_heaviside_smoothing_parametercan be set to choose the degree of smoothing (or "exact" for no smoothing).Fixes #1219
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.
Key checklist:
$ flake8$ python run-tests.py --unit$ cd docsand then$ make clean; make htmlYou can run all three at once, using
