Hi All,

Please could someone help me with the how to run a Riks analysis using displacement control and not force control.

Iam using this for plate buckling. So far I have run the eigenvalue bit and use the eigenvalue to substitute as my load in the static,Riks step but my proportional load is coming out greater than the critical buckling load for my slender plate and very small for my stocky plate. I think something is wrong.

Please your input is highly appreciated.
