Different parameters value in .ini file for different runs

Question

How can I have different parameters value defined in .ini file for each repeat in omnet using cmdenv? I have repeat value as 4 and trying to have different value of accidentStart and accidentDuration.

Answer 1

You can't. And shouldn't. The whole point of repetition is that all parameters have the same value, just the RNGs are seeded differently. So you get a different sample of the same distribution for every result value.

What you're looking for are iteration variables. Something like this:

**.accidentStart = ${100, 200, 350}s

This will generate 3 runs without repetition, and 12 runs with repeat=4.

and if you add

**.accidentDuration = ${duration=300, 450, 600..1800 step 600}s

this will multiply the number of runs by another factor of 5.

By default, iteration variables produce a Cartesian product of their respective assigned sets of values. But there are ways to change this, consult the manual for how.
