Access time steps with calculator filter (Paravis)

Hi all together,

I wonder how I can calculate the stress difference between different time steps?

Let's say my lower stress is at time instant 3s and my upper stress limit is obtained at time instant 6s. How do I calculate the amplitude? I.e. SIEQ_NOEU_AMPL = SIEQ_NOEU(t=6) - SIEQ_NOEU(t=3).

I hoped to access the time instants with the calculator filter, I just don't have a clue how :-(

Best regards,

Sometimes,

one should just continue to read through the menus just one more minute. Sorry. I just found a temporal filter named TimeDifference :-)

Sorry to bug.

But: Is there a way to access time steps with the calculator filter directly? Would make things easier inspite of TimeDifference-Filter. I am just thinking of calculating mean stress besides stress amplitude...

No it happened what I described earlier. How can I add the values of different time steps in order to calculate the mean stress value corresponding to the amplitude?
