Vensim uses models written in the Vensim modeling language. This language shares certain characteristics with other modeling languages. For your convenience, we have included translators from some of these other languages. These translations are somewhat incomplete, but do automate out most of the drudgery from the translation process.
After you have converted a model you will be left with a set of equations that you can load into Vensim. If you are using Vensim Standard, you may need to edit the equations using another text editor to correct any persisting errors. In Vensim Professional and DSS you can use the Text Editor to correct errors.
