Thank you for reply. Parameter Sweeps is a new word for me. I didn't find this word while looking for a way to automate wokflows. But now I do and now I am reading about Parameter Sweeps.
Other than Kepler, do you know any other workflow system which can do parameter sweeps until the required results are found?
