Optimization using Transient Response Analysis

Altair Forum User

  *** ERROR # 1381 ***
  Transient Analysis can not be performed during optimization.

 

Is there a way to run any other way to run an optimization with transient analysis?

Hi,

 

Can you share the entire .out file?

I might be pairing transient analysis with a wrong optimization response.

Hi,

 

It is not possible to run a optimization with transient subcase. 

 

Frequency response subcase is supported.

Altair Forum User

Is there a reason why optimization with frequency response is possible but with transient response it isn't?

Altair Forum User

Prakash,

 

Optistruct uses SIMP method for optimization.  SIMP method generally can be used paired with Transient Response.  That leaves me assume that transient response optimization is physically possible, but is not supported in Optistruct.  

 

Is that because of a problem with the algorithm or that transient response is simply omitted from optimization?

Hi,

 

Currently this feature is not supported.Its on roadmap for future release. once this is available we will update you.

Hi Rahul,

Does it supported in Hyperworks 14? or still not supported by the software.
