LAMTHK constraint on element set?
Altair EmployeeHi everyone,
I'm currently making a free-size composite optimization and I need to add Laminate thickness constraints to set's of elements throughout the part.
Is this possible or do I need to have more than one laminate to achieve this?
I've founded in the internet a release notes pdf and it says that this is possible but I can't find it in the optimization panel, only for the all laminate and not to a set of elems.
Thank you for the help,
Best regards,
Gonçalo

Hi Gonçalo,
Use LSET to apply LAMTHK on a set of elements. Card edit the DCOMP and turn on the LSET and refer the element set.

Hi Prakash,
Thank you very much for the reply.
Is this possible to use in free-size optimization? I can only find it in composite size optimization.
I need it in free-size because this will increase the rigidity of the structure in a area that will influence the results, so I really need to implement it.
Best regards,

Hi Prakash,
I had a better look on it now and I didn't understand what you meant by turn LSET on. I did now.
But this can only be done in one set.
Basicaly I need to assign the laminate to a DSIZE card and then create LAMTHCK for three different sets of elements inside the laminate.
Do I need to create more than one laminate to achieve this?

Hi,
How about organizing all three sets into another 4th set and referring this 4th set in LAMTHK?

Hi Prakash,
Two of the sets can have the same LAMTHK thickness but one of them must be different.

In such case you can have two laminates. I don't see a better work around than this.
