See #1001. This commit needs testing, and potential test_suite fixes before it can be merged.

thanks for testing! I will investigate further. Likely just sensitivity in these test_suite models, but good to double check.

@mathren i've updated the docs for this and fixed the testing instances. Please give the pr a look and we can merge it with your approval.

I've also just launched a test run on bluebear for the latest commit on this branch (TestHub link).

double_bh failed. 😭

[Debraheem]

ouch, I'll take a look.

I think i've identified the issue in the double bh test case, which is resulting from a small issue with recalculating omega when doing tides, but it's worth testing on a separate branch and then merging back into this one.
