Continuous kludge to keep pdivt > 0

[jonmaddock]

Ensure pdivt is kept positive continuously.

pdivt with continuous kludge:

And again, but with finer sampling resolution to show continuous nature:

I am bit concerned that you are redefining pdivt. If this code is ever run again then this change could be made repeatedly. Is there any chance of this happening?

I'm not quite sure what you mean; if you mean non-idempotence, then this isn't an issue: each time the model is called (with the same values) pdivt is calculated from other values (in the lines immediately above this change) and this kludge is applied. The same value of pdivt results each time. Does that answer your question?
