FSTOSZ Error #13: DLINK dependent DESVAR repeated in input data
Hello Everyone,
Here I am yet again with another OptiStruct issue I need your support for.
I am currently doing a multi-Phase Composite optimisation and I encountered a Problem with Phase 2: Size Optimisation.
When I activate the SDTOSZ command during my FreeSize optimisation, I receive faulty sizing-data. If I plug the xx.sizing.fem data back into HyperMesh and run a 'Check', I receive the following error message:
Error #13: DLINK dependent desvar repeated in input data. (17x)
This unfortunately happens in all other FSTOSZ data as well. I could not find any solutions or a workaround for this.
I would be very grateful if you could perhaps help me with this issue /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />
Best Regards and a good week,
Lennart

Altair Employeealso, do you have Ply balance constraint on your laminate?
If yes can you remove the same and try again?
Hi,
please find attached the OUT-Data, however there is not a lot written in it.
I made another test with a ply Balance constraint and appearently the Problem only appears when I do have a ply Balance constraint in there.
Is there a Workaround for when I do not use a ply Balance constraint?

Altair EmployeeHi,
yes, this is a known issue with Ply balance constraint.
If possible, please share an example model file to test at our end.
Hi Prakash,
Thank you for your help. I looked into the data again and I noticed that I did not use a Balance constraint. What I used was a constraint that binds the thickness of two plies.
If I use it, it works. if I don't it does not.

Can you share a screenshot of the card?
Hi,
please find attached the Card with all relevant info on the Balance-Constraint.

Altair EmployeeHi,
Yes, the issue is with Ply balance. If you have ply balance on the orientations other than 45 and -45, the analysis stops with that error.
Hi,
Thank you for your answer. Is this the way it is intended to be or will there be a patch in the future to include all other orientations except +/-45°?
Best Regards,
Lennart
Altair EmployeeHI,
Yes, this is the way it is for now. But, enhancement receipt is available to include other orientations as well /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>
Hi Lennart,
