Hi everyone,
In the Optistruct 13.0 Reference guide, it says that in the DSHUFFLE card can be defined a RANGE parameter.
However I can't find it in my software which is v13.0.
Can anybody explain why?
Thank you,
Gonçalo
Hi @GonPer
Unfortunately RANGE parameter cannot be added to solver deck via GUI. Enhancement request for the same already exists.
You need to add this manually to solver deck by editing the same in any text editor.
Thank you Prakash,
I will implement it in the model right away.
Best regards,
It's working, however I need to implement more than one RANGE parameter.
I've tried:
+ RANGE 1 20 21 30....
and
+ RANGE 1 20
+ RANGE 21 30 ...
And neither work because it only reads '+ RANGE in last'.
Is it necessary to divide in multiple stack cards?
According to help multiple RANGE can be included on a stack. Can you share the .out file please?
I will check if there is any warning or information about RANGE written in .out else I need to check with experts.
Hi Prakash,
I've suceeded using this, but althought shuffling is divided into ranges of plies, I did not achieved a converged study yet.
The way to go is to make a shuffling design variable for each range, using the same laminate.
There wont be any error in the .out file. I know it did not work by observing the results.
Just another thing I want to sugest, I'm making a cyclic symetric part and for this many simplifications must be made. If there were an option to glue plies together to be shuffled, it would help a lot. The current way is not possible to consider overlapping of different plies and the correct orientation. This because I need to make a super ply instead of using multiple plies with the different orientations in order to get a cyclic symmetric result. It's not difficult to implement and will expand Optistruct capabilities even more.
The objective would be to make one ply by joining multiple plies with different directions and overlapping, it's like a set of plies to be used in the laminate and etc...
Thank you and Best regards,

I am not sure if I had understand this correct or not, but you can have a different laminate with the you want to shuffle and use the same as design variable.

It would be better if you can provide a example file with the issue so that I can take the same to experts /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>
Thank you for all your suggestions.
I ve sent a pdf via Filetransferlink with an example.
Thank you Gonçalo @GonPer
