The feedback of a structure due to a step force?

      I am performing one-way FSI, where the Pressure input is a step function.

      the pressure input values were transferred from a transient value table where at t=0 to 0.11s P=0 then when t>0.11s P= 1 bar.

      I monitored the force on the structure wall and it was developing as expected

      The plot in Fluent - are you showing the fluid forces that are estimated as part of your solution? It seems that the fluid should exert some force on the walls. What you may be showing could be external forces - maybe you can confirm this?

      The force is due to the impact of fluid on wall and it is the same I exported to transient.
      I was expected that from 0 to 0.11 s no force exist mean no displacement but as you could see in the curve this was not correct

      can you please advise?
