Complex Eigenvalue Brake Squeal

Altair Forum User

Hello Experts,

 

I am trying to perform a complex eignevalue/ brake squeal problem on Optistruct 11. The error that i am getting is as follows:-

 

 *** ERROR # 1461 ***
 Card 'STATSUB(PRELOAD)' is not allowed for this subcase type.

 

I have used Generic as a solver instead of Modal Complex Eigenvalue as it doesn't support Statsub. 

 

Can anyone please explain how to resolve this issue. I have been following quite a few tutorials and have followed exactly the steps mentioned but cant get around this error.

 

Thanks

Hi Sritej Kalas

 

While creating the loadstep, change the analysis type to complex eigen.

I also recommend you to upgrade your version of OptiStruct

 

 

 

Have a look at these 2 tutorials from OptiStruct help which is similar to your case.
