Hi,
I have a model that is solved in 5 load steps. It is a static analysis with some nonlinear contacts (frictional and frictionless) and possibly nonlinear material properties.<\/p>\n

In the first load step, the bolt pretension loads and the mass of the model (acceleration in Z direction) are applied. These two loads are present in all the solved load steps.<\/p>\n

In the following 4 load steps, acceleration in +X, -X. +Y and -Y are also applied\/added to the model in consecutive load steps. <\/p>\n

Now, my question is this: Is it possible to return the model to its position at the end of load step one, before starting the solution of the next load step?<\/p>\n

So after applying the loads in load step one, the structure is in POS1.<\/p>\n

The loads in load step two are applied (e.g. acceleration in +X) and solved. The structure is in POS2.<\/p>\n

Before solving load step 3 (e.g. acceleration in -X), the model should be returned to POS1 and then solved. This should be repeated for all the load steps after the solution of load step two.<\/p>\n

I hope I was able to describe the problem well enough.<\/p>\n

Thanks in advance. <\/p>\n","protected":false},"template":"","class_list":["post-316794","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
