Hi,

 

No laminate/property is refered for freesize setup (DSIZE card). Please check, update and run the analysis.

Thank you for you'r help !

But unfortunately now I have the next error..

 *** ERROR # 6010 ***
 DCOMP 2 defines constraints for STACK 3 which cannot be
 satisfied. These constraints are initially violated but they do
 not involve any designable plies.

hi Ann123,

 

Since I dont know which laminate you have referred and to which DSIZE, I can't really suggest a solution.

 

Please share the modified deck to the dropbox link in my signature below

Hi Ann123,

 

Balance constraint is used when there are +45 and -45 plies are available. In your laminate there are only +45 plies.

 

Also, remove membersize constraint on DCOMP

Hi Prakash,

I tried to solve the problem that way but I think there are some more faults..
If I delete the balance in the free size than nothing is happenig and if I delete the balance in the composite size than my plys are empty. It is to despair..;)

Ann123,

 

Even with Balance the size DVPRELs are empty. Looks like plies did not referred in the size parameters. Can you cross check this?
