Query to reset the displacements/strain to zero

[Shubham Tiwari]

I am trying to simulate a time history analysis of a retaining wall along with foundation and backfill soil. I have already carried out the static analysis and consequently importing the statically generated stresses via predefined field option. Before performing the time history analysis, I want to make the displacements and/or strains all over the model to be zero. Can anyone please let me know how to do this.

Would be good to know what software you are using.

i am using Abaqus software

run the time history as a separate loadcase ?

run the time history as a separate model (not a good choice, as two models will inevitably get modified separately during the ensuing analysis; but with discipline can work)

Abaqus has a special "annealing" procedure for that - check the *ANNEAL keyword. You could also use the import functionality (*IMPORT) with UPDATE=YES to reset the reference configuration.
