It is very important to know whether a model has solved properly, and if not, to locate where the problem lies. This sheet in the model workbook satisfies this need. The two top matrices give the final iteration values of the target and change variables for each time period. The bottom two matrices give the starting iteration values each time period. In this example, zeros in the top red matrix for all time periods for all target variables shows that a satisfactory solution has been calculated. If there is a problem and some cells are not zero, then diagnosis of the solution problem can focus on the appropriate variables and time periods where target variables have not converged to zero. You should always check this sheet before saving a solution for safekeeping.
