| -- | Refinery Ops - RHDS-SIM | Do not warn about failing to match target MOC if ""Integrate Activity"" and ""Cumulative Metal Profile"" options are active. |
| If ""Integrate Activity"" option and ""Cumulative Metal Profile"" are active, RxMetRate which is a function of actual metal removal rate is used to update the metal array which is then used to calculate metal accumulation rate instead of using the metal distribution function approach (in METALDEACT subroutine). | ||
| In other word, during a typical ""Aging"" study only the first Predict (base) case utilizes the metal distribution function, the subsequent cases with iActivity=1 && iMetalProfOpt=1 will not use the distribution function but instead simply ""add-on"" the identical amounts per reactor bed elements of actual metal removed (in ELEMNT routine) to the last case metal profile. | ||
| We only want to warn about failing to meet target MOC when the metal distribution was used (iPS2nd=0 if there is no age increase). |
