Restore Input Data (Input menu)
Use this command to RESET the Flowsheet Calculation Status. It deletes any previously calculated results for the current flowsheet, allowing a complete reinitialization of all columns, recycle streams, CALCULATOR results, etc. back to their initial input data.
This feature is particularly useful if a particular what-if scenario involves substantially different operation from the previous run, or if multiple CALCULATORs need to have their results (R array) reset.
