Hi,

 

Im doing a Shape optimization which search the optimum height of my designspace to reach the min weighted Frequency of 3 modes of my Part.

The optimization runs more than 30 iterations if I set the objective to maximize Frequency but it runs only 2 iterations if I set it to minimize the weighted Frequency.

The reason why it stops is that OptiStruct doesnt Change the height / volume of the Designspace in the second case:

 

with Frequency:

1. Iteration: 8,57152E+05

2. Iteration: 8,38065E+05

3. Iteration: 8,18978E+05

4. Iteration: 7.99891E+05

 

with weighted Frequency:

1. Iteration: 8.18978E+05

2. Iteration: 8.18978E+05

 

Ist the same Model with the same Setup. Why it doesnt work?
