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
