Problem Optimization

Hello everybody,

I'm trying to do a composite optimization following the tutorial that described a monocoque FSAE optimization; I made the first step (free size optimization) but when I try to edit the ply shape for manufacturability and I try to start the second optimization, I have an error:

 

 A fatal error has been detected during input processing:


  *** See next message about line 31 from file:
      C:/Users/Salvatore/Desktop/Altair ottimizzazione manuale/Ottimizzazione/Ottimizzazione con DOF
   'DESOBJ(MIN)=6'

  *** ERROR # 1041 *** in the input data:
  Card DESOBJ conflicting with previous DESOBJ, MINMAX, or MAXMIN data.

 

I noticed that after the first optimization are created automatically other objectives, other otpimization control, response and constrains; maybe they could be the cause of this error?

Thanks
