Use the mode shape from eigenfrequency analysis as the initial condition for the next step

Hello,

I want to use Step1:eigenfrequency to obtain the mode shape of the first bending mode; then in the Step2:Stationary, I want to use the Z displacement of the mode shape in step1 as an input to define the z velocity for the Velocity(Lorenz term).

Dese anyone know how to do it? Any suggestions would be appreciated.

Best regards, Xianfeng
