1 .ic is enforced at time=0, eg an initial condition for an oscillator.
Nodeset is a hint to the Newton solver, so it will start "near" the true solution, but the actual time=0 solution may be "far" from the nodeset.

If at first you do succeed, STOP, raise your standards, and stop wasting your time.
