Reply To: Is choice of supports in Inertia Relief important to consider?

[Rameez_ul_Haq]

thank you for your answer and I will also have a look at the discussion which you shared.
I couldn't understand what you said in your second answer. I mean when I conduct a static structural analysis by turning large deflection OFF and inertia relief ON, then I need the supports somewhere inside my model in order to avoid the stiffness matrix being singular. After conducting a large deflection OFF and inertia relief ON analysis, I can obtain the resulting accelerations from the solver output file. Now, what I was asking is that if I re-conduct the analysis by turning large deflection OFF and inertia relief OFF and inputting the accelerations obtained from the solver output file and also by using the same supports as used with the previous analysis, then would I be getting the same displacements and stress results in my model or not? I think they should exactly be the same because I don't see any difference between these two cases.
