Can table loads be used in a mode-superposition transient? Do you have an example?


Yes, here is an input file showing the mode-sup transient procedure. It just uses 5 time points, but the procedure would be the same for any number of time points. The only difference would be that the time/acceleration table would be in a file and *TREAD would be used to read the data into the table array, acel_val.
