[TRNSYS-users] Different results by different Trnsys versions?



Dear all,

I am using two Trnsys versions. New decks I create in the actual Studio (release 16.01.0003). Since the accompanying TrnEdit always runs into some access violation I use an older 16.01.0000 for parametric runs. Now I discovered that the two versions calculate different results for one and the same deck with identical parameters! For some results the difference reaches up to 5%!!

Has there been a modification to the solver? Any other explanations?

Cheers,

Björn
