Dear experts,
Suppose there is an array which is changing with respect to time as below:

Time(sec)===> Force Value(N)
0 ===> 0
1 ===> 20
2 ===> 50
3 ===> 70
4 ===> 100
.... ===> ....
1000 ===> 500
This array is applied on the 1st element nodes. After some time lag (say some 3 sec) a new array results as mentioned below is applied to the next element nodes.
Time(sec)===> Force Value(N)
3===> 0
4===> 20
5===> 50
6===> 70
7===> 100
....===> ....
1003===> 500
It can be noted that, for the next element the base point (the initial force value '0' is now starting at 3 sec) is changing to 3 sec. How to apply these two arrays so that transient forces can be applied properly as mentioned above ? This is to be applied in Mechanical APDL.

Regards-

Firstly you do yourself no favours by posting incomplete questions. I
have looked at the Forum and seen the full question but I wonder how
many people who read XANSYS via email would bother.

My thought is that this sort of loading is easiest with a Table array
with the zero column being time rather than a straightforward array.

What I quoted is exactly what was received by email subscribers. The
Forum post shows you have edited three times but these edits are not
