Explanation for very large maximum constraint violation % in the first iteration
Greetings,
I am performing a free-size optimization (iteration summary given below) and trying to understand the explanation behind maximum constraint violation %. So far the following is clear:
- If constraint violation > 1% : status is V (violated)
- If constraint violation < 1% : status is A (Active)
- Large constraint violation % could mean that the constraint is too tight and that the problem itself is ill-defined.
- the difference between regular and soft convergence is understood as well
Problem definition: The thickness of an insert is defined to be the DV. Two stress constraints are defined. The objective is a stress minmax formulation.
Question: I am unable to figure out whether the large constraint violation % implies a critical issue. If yes, how does one rectify the problem?
