In XFMEA/RCM++/RBI only, the Calculation Options window lets you choose which system(s) in the failure modes and reliability analysis (FMRA) will be calculated and which application will be used to perform the calculations.
If the FMRA has multiple systems, or if it has records synchronized with BlockSim, this window will appear when you calculate the FMRA.
In the What items do you want to calculate? area, you can choose to perform calculations only for the system that is currently selected, or for all the systems in the hierarchy.
In the Calculation Method area:
The Calculate using BlockSim option is available only when there are records in the FMRA that are currently synchronized with BlockSim. If you calculate using this option, the software synchronizes all records and then returns results based on the reliability-wise configuration of the synchronized RBDs in BlockSim.
The Calculate using current application option is always available. If you calculate using this option, the software will assume a reliability-wise series configuration among all the records in the FMRA.
