Effect of change in material density/modulus of elasticity in optimization

Altair Forum User

Hello All,

 

Can anyone tell me how does optistruct uses material data to attain an optimum design?

 

For example:

 

We have run a model for topology optimization with material magnesium and also with material Aluminum by keeping the density same but varied the modulus of elasticity accordingly.

 

How does optistruct uses density/modulus of elasticity during topology optimization ?

 

Its quite urgent, any suggestions are highly appreciable.

 

Thanks in advance.

Hello Praveen,

 

It depends on your optimization problem. What is your objective and constraints?
