General question about multiple steps in solid mechanics

Hello everyone,

I have what may turn out to be a question which makes me look like a dummy!

I have been looking in the documentation for information regarding multiple steps in a simulation. For example lets assume we have an cube which I compress, I then wish to twist the cube and then in a third step I wish to compress it further. This is an arbitrary scenario but sets the scene.

How do I export the stress and strain in the cube as a result of the first step into the second step, and then again, how do I take the stress and strain induced by the second step into the third one.

I have found a good example which looks at the initial stress and strain, (Example is "Thermal Stresses in a Layered Plate"). The example is great and shows me how to pass on the stresses from a first step into the second one. I export the:

solid.sx, solid.sxy, solid.sxy, solid.sy, solid.sz

values in the second step.

I have a couple of questions I would like to ask.

1) what does "solid" in "solid.sx" refer to?

2) is there a general case for this? For example how would I take the stresses after the second step into a third step?

I hope this question makes sense!

Many thanks for reading. Im very interested to see what people say about this.
