I understand there is a utility called stel2ven.exe that is supposed to do that. Following the suggestions in previous posts I have been able to operate stel2ven.exe. However, the output file is almost empty. I am sure the problem lies in the input file that I gave to stel2ven.exe. How should I prepare.Featured. Some features applications of Ventana simulation products: View More Featured Items. Data Science meets the bottom line. Vensim can be used to put big data in context, by incorporating the learnings from big data in simulations that account for organizational structure and finances.If you installed the sample models, you will have a utility named stel2ven.exe that converts Stella and ithink format files to Vensim format. Vensim does not support the same graphical representations used in Stella and you must therefore save your Stella model as equations.
