Hello 

 

I'm trying to make an mnf file with preload.

 

I already made mnf file without preload using CMSMETH, ASET succceeded.

 

However I want to make an mnf file containing the preload, so I used the preload, LCID and SCID options of CMSMETH card. 

 

As a result, a mnf file is created, but the preload is not included.

 

Is there anyone can tell me how to solve it?

 

Also I want to know what this info means and how to solve it.

  
 *** INFORMATION # 3448
 Lower bound of frequency interest (V1) has been moved to 
 negative infinity to capture potential negative modes in
 vibration analysis with preload.
  

 

Thank you.
