Infusion / Mash Calculators

Hello,
Is there an infusion calculator where the final qt/# can be entered first? I would like the intermediate steps and thicknesses to be calculated ‘automatically’ (entering temps for each step of course)  based on the desired final thickness.

Also is there an infusion calculator that can be use for decoction mashes?

Thanks,
Cheers,
Mike

Back in the May/June 2005 Zymurgy, I had an article discussing this topic.  I had written my own code to automate this calculation but it is not compatible with new operating systems (actually the problem is high speed processors).

Using a spreadheet, you can fairly quickly converge on a solution.  So the automation is not a big deal.

Thanks for the link.
