Define the relative displacement between two points as optimization constraint

Hi,

Is there a way to define in INSPIRE relative displacement between two points as an optimization constraint?

To be precise, I am interested in giving constraint to relative displacement only in a certain direction.

Thanks in advance

Hello Yosef,

Could you provide us an example of what you want to do ? (picture)

Hello Thomas,

I want to use such a constraint as workaround to prevent torsion in bending the beam, when the load is not symmetrical.

Did you try with this ?

This constraint does not meet the need because it is an absolute constraint. I need relative constraint.

That was my concern also. Thus it's not possible to do it Inspire, but you can do it with OptiStruct using DRESP2 card.
