ABAQUS - same model, different steps

[dimvoly]

I've got a bit of an organizational question:

-I have the same model that I need to subject to different time histories.
-So one model and I need to do the following
--Static Load (pushes it into non-linearity)
--Pushover (pushes it into non-linearity)
--Cyclic time history loading (ends up non-linear for sure).

As you can see essentially each analysis starts from a base case of no stress anywhere, so undeformed model.

I could copy paste the model inside the same cae file but then if I make a change in one place I'd have to make changes to other places. Not very organized since I'd have to track what I've changed across several models.

In essence I'd want the source model to be the same but the non-linear steps I apply to it need to be different. I guess I could try an initial step and then different restart analyses? That would decouple the base model from subsequent steps.

Any ideas welcome.

You can activate/deactivate STEPs. I would use only a single model and perform RESTARTS from a base state.

Thank you for that portliner. I've done that before with the activate, deactivate. What I might do is use a script to activate all the relevant ones at a time once the file is large enough.
