Why following force displacement is lager?
Altair EmployeeI am practice the example like this connect
https://altairuniversity.com/analysis/structural/nonlinear/beam-comparison-to-nlstat/
but I don't know why I set the coordinate and assign the force
assigned beam's displacement is lager than doesn't assigned beam

Hi,
With Follower force, load follows the geometry as it deflects for this you need a coordinate system.

Really thanks to your reply
but I still don't konw why we need to set coordinate to it
and when we don't set coordinate means the analysis is wrong?
thanks a lot

Hi,
Try this without coordinate system using FLLWER and FORCE1

@Prakash Pagadala thanks to your apply
and I use your model to set coordinate for case 1 and doesn't set for case 2
at displacement result are the same. What are they mean

Hi,
You dont need a system with the model I shared.
The model I shared uses FLLWER card to tell the solver that the load applied (FORCE1) is a follower load.
