I am interested in using solver but I do not want solver to autocalculate
all of my sheets. How do I set solver to just work on one area of a sheet
without it interfering with the rest of my sheets and calculating them?

Kevin,

Solver only works with ranges in the active sheet. Whatever
formulation you have looks for the cell values on that sheet only and
places the solution values on that same sheet.

yes, but solver apparently turns on autocalculation on the side and
calculates all of my sheets. you can test this simply by running solver on
sheet 1 and having something that needs to be calculated manually on sheet
2. if you run the solver on sheet1 and check sheet 2, you will notice that
sheet2 has also been calculated as if someone pressed 'f9'.
i am trying to stop solver from calculating stuff on sheet2, any ideas?

Kevin,

I'm not an expert on Recalc but solver has to update the solution cells
which is a Recalc. How about this. You create your optimization model
in another workbook (Book2) with its data linked to the original
(Book1). Close both workbooks. When you reopen Book2 to optimize,
select the Don't Update links option so Book1 is not recalculated.
