Dear support team,

I have ran several topology optimization simulations using the stress constraint, with a volume minimization objective.

I have added manufacturing constraints : member size and pull out direction.

At the end of the optimization, it seems that the members do not respect the max size :

 

It looks like the optimization as stopped after a maximum number of iterations, before the constraint can be reached.
How do you explain that the manufacturing constraints are not met ?
Is there any way to find some diagnostic information or optimization report ?

Thanks for your help,
Marin

Hello Marin, 

Let me check and get back to you on this.

Hello Marin,

You can use Monitors for Mass and Volume and see the solution convegence for optimization from the details panel. This will provide you some idea on the manufacturing contraints. Let me know if this helps.

Hello Devendra,

Thanks for your reply. I was looking for more precise information : is it possible to know the criterias that will stop an optimization in Discovery ? What is the maximum number of iterations for example ?

Hello Marin, 

Let me check if we can get this information and will get back to you.

Hello Marin, 

It is not possible to check the number of iterations when the solution will stop directly, when we define the monitors we can check solution progression and once it reaches the maximum iterations settings of 300, it will stop and you will get a warning message in the notifications mentioning the particular constraint has not met. 

Ansys Discovery also provides you an informational messages indicating partcilar constraint might not be correct and will be auto-updated as per the requirement to solve. 

Let me know if you have any further questions on this. 

Regards,

Devendra
