Improvements are made to the consistency checking of the time point data for the execution
of modal integration and direct integration time history analyses. If the number of time
points to be processed by these analyses exceeds the maximum allowable 4,000,000, the
following error message is now given and the indicated action taken:
**** ERROR_STTINT -- Maximum allowable number of integration time points
(4 million) exceeded for loading 1002
.
Scan mode entered and analysis terminated.
