Advanced temperature calculations...Need data!

I'm planning on doing a couple of brews (AG, infusion mashing in cooler) for which the built-in temperature calculations in Beersmith won't work. For example, a stovetop cereal mash followed by infusion mashing with the rest of the grains, or a sour mash of a portion of the grain bill.

I know Daniels gives the information I need (heat capacity of grain, etc.) in Designing Great Beers, but I'm hoping to find an online reference so I don't have to check it out again from the library.

Anybody have a good link to some information, or perhaps a spreadsheet designed for such calculations?

Thanks!

I don't know if these will help...I had googled "beer math" a couple hours ago looking for a specific formula, here's a couple of links I found.

Therre's also an article on creating brewing spreadsheets on BYO.

I don't know if any of this will help you, specifically, it's just what I had dug up this morning.
