Sequential Analysis

Hi,

I want to carry out a sequential analysis in Optistruct.

The deformation is carried over in every step.

The load point changes in every step.

How to do such simulation? Is there any sample deck?

    @aravind_bhandiwad you need to carry on a sequence of NonLinear Subcases, and link them through a card called CNTNLSUB(Continuation of NL Subcase).

    You will create a initial Subcase #1, them for the others you will go inside the Loadstep and enable the option 'CNTNLSUB'. 

    There are basically 2 options: YES or SCID. 

    If you use YES, them the continuation takes the previous loadstep. 

    If you define a SCID, you should point to the particular LoadStep you're looking to continue from.

    Please take a look at the documentation, and search for CNTNLSUB for more details.

     

    You'll probably find a tutorial for that in the documentation, under OptiStruct Tutorials. Have you take a look there?
