defining load with arbitrary time history

[raham]

How can I impose a load with a time history to an arbitrary node ?
And can we define dynamic uniform load with an arbitrary time history?
Thanks

1. use a path time series inside a plain pattern which contains a load on the node you want.
2. you can use use a UnifromExciationPattern for unifrom ground motion, or if you want
to apply the loads directly, use 1. above and a dynamic analysis .. just give some mass.
