Hello 

I have a model that is built in plantsimulation 10.1.5. When i start it in plantsimulation 12.2 i need to change methods that serch seek through Contentlist of a storage. In 10.1.5 it use  for i:=1 to kob.capacity loop and to avoide index out range I cange it to for i:=1 to kob.ContentsList.ydim loop. Everything looks like it work as it shuld. But the result from the 10.1.5 is 4526 units and from the 12.2 version the result is 4292 in the same time. Have any one hade problems when they change a model from a erly version to a newer version that the result change drastically?

Hello Jfinnberg,

 

in V11 we improved our random number generator. So if your model uses distributed times, this can explain the different results. You then would have got the same variance in V10 when you change the seed values.
