@RISK Changes Formulas During Simulation

During a simulation, @RISK rewrites any cell containing one or more distributions so it can identify which distribution Excel is recalculating. This rewrite also improves calculation efficiency.

After the simulation finishes, @RISK automatically restores all formulas to their original form.

If Excel crashes before @RISK can restore your formulas, you may find that they all begin with RiskSDS. You don't need to rebuild them manually.

To restore the original formulas:

1. 1. Set the number of iterations to just 2 or 3 to speed things up.

   2. Run a simulation.

   3. When the simulation finishes, @RISK will automatically restore all formulas to their original form.

   4. Reset your iteration count to its previous value before saving the workbook.

This returns your formulas without any manual reconstruction.
