Hello
my friend
Now I understand
that I want to model just a moving force, as you said moving oscillator is
general. I tried model moving force but there is some error and problem in my
these models
I make 3
models, a model with moving force; second one with moving oscillator and third
one with a constraint force in the middle.
Again Zero
pivot warning was shown for two models, while all of my BC or joints were
perfect defined
After run of
each models, errors and warnings come, could you help me to solve these
problems?
I attached CAE
file too.

-There
are 2 unconnected regions in the model.
About
20 number of this warning :
