Hello,

I thought the time step during RRA is constant (typically 0.001). However, I incidentally found an RRA output where time step were not constant during the analysis:

time
...
0.48
0.4808624
0.481
0.4818624
0.482
0.4828624
0.483
0.4838624
0.484
0.485
...

I would be grateful if someone could tell me why this kind of thing happens.

Best regards,

The controls computations are performed and then updated every control time window (e.g. 0.001) which is a periodic event. The integrator is variable step and more (e.g. intermediate) steps can be necessary to achieve the desired accuracy.

Thank you for the reply. Then I will check if there's any problem about the tracking accuracy just in case.

Best regards,
