…ary terms. Auxiliary terms will only be checked if NaN every so many increments rather than every increment. Testing the Cahn-Hilliard application resulted in an ~25% decrease in computation time.

There was a problem hiding this comment.
I suggest reverting to checking every time step for the time being.
…wer, it provides users better debugging information.

Fixing these to more closely resemble the process for explicit terms decreases computation time greatly. These changes have been tested on the Cahn-Hilliard app to produce identical results with an ~25% decrease in computation time.
