You can select the Sum Load Sets option, if you want Creo Simulate to merge the loads of all the selected load sets. If you do not select Sum Load Sets, results are calculated separately for each load set. If you select Sum Load Sets, Creo Simulate assumes that all load sets act simultaneously, and reports results for a single load set containing all loads in the selected sets.

You can use the Sum Load Sets option to mix loads with different functions in the same analysis. You cannot mix load sets for a dynamic time simulation using the function impulse with load sets using any other function, but you can sum a series of load sets that all use the function impulse.

The Sum Load Sets option is available on the following dialog boxes:
