Thanks for the quick reply.
I tested the code and if I now set Add Data to 100 steps, my update
routine is indeed only called every 100 steps. However after a few
hundred steps the simulation slows down and I finally get an out of
memory error (see below).

But don't worry. Take your time to solve this problem for the next release.
For the time being I have a "if ((schedule.getSteps()%100)==0)" line in
my function and I keep the data in a class variable so that I can return
them for the other time steps.

Best regards,
  Axel
