HF-4040: Process and Shape Optimization Using Incremental RADIOSS

Altair Forum User

Hi, 

 

Anyone can tell me why morph at blank but not the die?

 

Is it possible to morph at die and run the optimization in incremental?

 

Thank you

Hi,

 

optimization is carried on the blank because we need to finalize the final component shape such that it is manufacturable. Variables such as corner radius, blank thickness and  edge fillet radius effect the formability results.

 

The die is generally morphed (compensated) after running the spring back analysis

Hi,

 

I observed there is some split or thinning from forming result. So in order to optimise, I need to morph the blank, correct?

 

But the blank is flat, how am I going to morph those shapes?

 

Thank you very much.

Hi,

 

Can I ask are the 

 

initial value: 0

lower bound: -1

upper bound: 1

 

must be those value? Cannot like upper bound 5, lower bound 1, initial value = 3?

 

Thank you very much.

Hi,

 

can anyone please tell me is it possible to carry out stochastic analysis after run incremental optimisation in hyperform?

 

Thank you very much.
