Displacement control load

[Anonymous]

helo,

Is it possible to apply displacement controll load at free node? (I want to apply displacement instead of force at free end of a cantilever beam and check value of generated force or stress for that particular displacement)

Is it possible to apply displacement controll load at free node? 

Not directly, you have to apply support with very small (neglible) elasticity on such node.

WHY IS IT SO?

[Rafal.Gaweda]

Because there is no such load on free node in Robot.

BUT WE CAN GIVE NODAL FORCE OR MOMENT AT SUCH FREE END AND WHY NOT DISPLACEMENT? ANY SPECIAL REASON?

what is this?

sORRY BUT EVEN WHEN I APPLIED SPRING SUPPORT, THEN ALSO IT IS NOT WORKING. HERE I AM ATTACHING THE FILE

I WANT TO STRETCH AXIALY IN ux DIRECTION... FOR THAT I AM ASKING. IT IS NOT SHOWING DISPLACEMENT OR FORCES IN THAT CASE

Upps, sorry.
I have not checked results values.
Let's assume the workaround does not work.
