Hello everyone. I study Civil Engineering and I work on a structural-geostatic task. I would like to ask how could I insert initial stress conditions in a static stractural analysis.Is this possible only with APDL commands or there is another way? My analysis has multiple steps and I would like to insert in situ stress conditions between 0 sec and 1sec(steo 1).
Thank you in advance.

check the INISTATE command in ANSYS help, also more info at:

Thank you very much for the answer,Aniket.Yes, this is the command that i use in my analysis but i haven't managed yet to find a proper solution.
In my 2d analysis i use a simple square geometry with soil properties(Young's modulus,Poisson's ratio,soil dens γ.What i am trying to achieve is this:
I want the program initially,before any other loads application even gravity, to calculate the geostatic in situ stresses of the ground(s=γxH,H=height) properly
and give me as result this stress gradual increase,from the free surface to the bottom,according to equation. I will be glad to hear any ideas about this problem.
Thank you in advance.
