Dynamic optimization

Amasker

Hi，

I recently used Optistruct to optimize the design under dynamic loading (collision), but I don't quite understand the optimization principle and process under dynamic collision.

 

For example, I used the maximum displacement of a node as the maximum constraint, and found that the .out file is shown below.There are 20 subcases ，and 20 displacement responses，why？

here is .out file.

 

Is there any related reference tutorial?
