Is it possible to import models in AnyLogic from other simulation tools?
Yes, currently AnyLogic 6 supports import of Vensim® models. Now you can simply open Vensim® model (File|Import|From Vensim menu item) and it will be converted into AnyLogic model analogous to the original Vensim® model so you can easily continue developing it in AnyLogic. AnyLogic 5 supports converting models from iThink/STELLA, you can find convertor on xjtek’s Utilities web page.
