Using results or a previous simulation as initial condition and change loads.

I am running several static structural simulations of PET fixed-fixed beam and pre-compressed at its ends.
First of all, I have solved the initial pre-compression at the first step.
Then, I want to use the results of this analysis I have saved, to run several static stepped simulations (in the same way as www.comsol.com/community/forums/general/thread/25586/ ) in which I have to change the conditions (I have to add a prescribed displacement from the resulting point of the previous analysis).
How can I use the solution of the previous solution as initial values? How can I change the conditions, taking into account the previous solution?
Thank you in advance.
Kind Regards.

Check the settings of the "Derived Varibles" sub-node under the Solver nodes

Good luck

I didn't find any subnode named "Derived Variables" under the Solver node.
If it could be helpful, I have uploaded the model to be used as starting point for my static stepped simulations at this link: www.zshare.net/download/991656753397dd7d/ (the file of 5.4 MB seems too large to be uploaded here).
Thank you in advance.

you are perfectly correct, my fault I meant "Dependent Variables #" subnode
Normally ypou should EDIT Clear all Solutions Edit Clear all Mesh, File Reset Model before uploading then the model is small and "clean"

What should I set on "Dependent Variables #" subnode in order to set as starting point the results of the previous simulation (the file I have submitted) and to apply a stepped prescribed displacement?
