Multiple study steps : Stationary and Time dependent

Hello, I am simulating a vibrating mechanical structure. I need to apply a sinusoidal exictation force (Fex=F0.sin(2.pi.freq.t)). My structure is pre-stressed by a stationary compression force P0. Using only the Time Dependent study results in big oscillations of the structure at the beginning due to the sudden application of P0. I added a stationary study in the computation sequence in order to calm the initial oscillations but I keep receiving error messages about the variable 't' that is apprently not defined in the stationary study. How to solve this? Thanks Khaled

Hallo,
define t=0[s] as a global parameter. That's all.
