save the state of structure and continue to other analysis

[nahid2011]

Hi Sir/Madam

I know my question looks very simple ... but actually I have simplify it

Assume a 2 node element (A,B) ... I want to push node A in X direction (Xa=1 cm)

and read the force and stresses in the element and then push node B in Y direction to (Ya=1cm)

how I can script such an analysis?

Would you please inform me if there is a simple example available ?

Kind regards

not quite sure if i understand you correctly .. there are 2 options for moving a node
1) Displacement control - in which you have some loads applied and seek to determine the load factors needed that when multiplied by the reference load will move the node you specified by the amount you specify. The other nodes move as a consequence of the loads applied.
2) Imposed motion - in which you specify the node displacement as a boundary condition. This is done using MultiSupport load pattern. The rest of the nodes move because of this boundary condition.

Thanks a lot Dear Sir

yes I'm looking for the first option ... would you please provide me examples of "Displacement control" analysis (?) ... (By the way it is a type analysis, isn't it?)

and also let me know about the examples of two stage analysis, in which you can store the results and state of the structure in the end of each stage ... and proceed to the next analysis?
