DebuggingBefore attempting to run the simulations, make sure your version of excel is configured as follows:Selecting the cell will display instructions.1Install Solver2Make sure the macro function can use SolverIf at any time Solver reports an error message after a macro has been run, simply uninstall the Solver Add-In from the Add-Ins menu (found under Tools), and reinstall Solver as described under "Install Solver".If the above has no effect on the outcome of the error message, try guessing another value for the insulation thickness. Solver sometimes converges to different values depending on the initial starting value.
