  Hi,
  
  Is there any way to do Static self weight analysis before Transient time dependent analysis like pre-stressed Modal analysis. Because i would like to analyze a structure undergoes time varying sinusoidal load with constant 1G acceleration condition.
  
  Thanks & Regards,

  Hi,
  
  You can assign two steps in transient analysis. Apply 1G acceleration in the first step and keep it throughout the simulation (the substep size can be large in the first step so it won't increase much of simulation time). Introduce the sinusoidal load from the second step.

  You can turn off Time Integration during step 1 to obtain the static solution, then turn Time Integration on for step 2.
