Edge cases

[btupper]

Currently, a particle can drift beyond the extent of the elements (either goes ashore or drifts beyond the open water edge. Is that what we want?

Does it happen frequently along the coast? Or more at the open boundaries? If it's just the open boundaries, no problem.

Another option would be to clip it to the edge if it drifts out.

[btupper]

Clipping is how it works now - for the track that exits it is "done", but the while loop continues for all other tracks until they all exit or the max iteration is reached.

You can see that two exited early (short orange to south and the long green to the north) but the third (blue) reached that max iteration.

[SeascapeScience]

Short orange looks like it could be a problem. Can we clip it back to the nearest in-domain location? I have to think about that.

All points are in the domain. If “next” point is out then the iteration stops.
