I am guessing you are sampling something every 1000s so you have event points at these steps. Use the simulation flag -noEventEmit
to not store those in the file.

Thanks for the input.

I was looking through the official documentation for Dymola for some time, but couldnt find anything that
associates to it. I found this from the official manual:

An Output interval group to specify how often results shall be stored. It can be specified in
terms of Interval length or Number of Intervals for the simulation. By default the results
are also stored at discrete events. For the Simulation time unit button after the interval
length input line, see below.

Maybe it is default option to store values at 1000s s (sometimes at 100s s also) ?

Can you provide more details how to try that simulation flag option?
