Customize objective function

Altair Forum User

I want to create a new objective function but i do not know which code should be used.

 

For example, i want to have an objective function to minimize interface failure with an equation f = sum of normal stress * shear stress from each element.

 

Thank you

Hi @Alan

 

You can use Equation (DEQTN) to create a custom response.

 

Please refer for the same on OptiStuct help and let us know if you have any questions.

Hello @Prakash Pagadala

 

I am not able to find corresponding help of Equation(DEQTN) from Hyperworks Help Home. I saw *equation() but I do not understand its meaning at all. Can you please send me the link of it?
