How can I input an acceleration type seism in Mechanical Engineering (FSI) ?

      Hi !
      I want to simulate the behavior of a half-filled cylinder with water faced to a seism. The goal is to get the stress and strain values on the cylinder structure
      Thus I use a coupling between Mechanical and Fluent, then I want to apply the same acceleration on my fluid and my solid in the X direction.


      I succeed in inputing my accelerogram file on Fluent in using a transient file and in Mechanical by copy/paste with multi steps in the tabular data.
      However as I use a fluid solid interface, I have the error message "The fluid solid interface load is not valid for multi-step analysis.".


      So I change my analyse settings, I choose one time step at 25s but now I don't know how I can add the 4096 values of my accelerogram.
      I have searched whether I can input it in using a function in X Component without success...
      I enclose the type of accelerogram I use.


      Thanks !

      And this is my model.

      I have succeed in resolving my problem.
      I have used one time step and in acceleration, I have imported an XML code with the informations of my accelerogram :
