Hello,

For my school project i need very basic 2d room airflow and gas concentration simulations, i can use some opensource software and my own GUI wrapper for it, so i'm looking for something very simple and easy to script.

So far i like ANSWER package for it's nice syntax - all you have to do is put a couple of lines and it just works

So my question - is there anything like answer but free?
Or maybe there's something designed specifically to my task (2d room flow)

thanks
