Problems with size optimization

Altair Forum User

Hello!

I ty to do optimization of composite structure from one of Optistruct tutorials, so at the stage of size optimization I have some difficulties:

 

*** ERROR # 1481 *** in the input data:

 Control card without the name in the first field.

  (Possibly missing trailing comma in the preceding card,

   missing BEGIN BULK card or line before BEGIN BULK has trailing comma.)

 

If I remove control card OMIT, appears next message:

 

*** ERROR #  622 ***

 PLY     91100 does not contain any valid plate elements referencing a

 PCOMPP card.

 

File with model is attached here:

I've just begun learning HyperWorks, so could you help me?

Hi,

 

Delete the PCOMP property and OMIT card and assign PCOMPP to fairing component. Run the analysis and check if you are through the error message.
