MMO, Pattern Repitition, Master and Slave
Altair EmployeeHello!
I am setting up an MMO with 6 configurations. In the first 3 of these there are 3 design variables that have no intermediate relations. In the other 3 configurations there are 4 design variables where the 3rd is constrained to repeat the pattern of the 4th. But the 3rd that is constrained to repeat the pattern of the 4th is also in the 3 first configurations. My question is:
Can I define the 3rd DV to be a repeated pattern of the 4th in 3 of the configurations and at the same time define it as a master pattern with + COORD in the three other configurations?

Hi,
I think it should be possible, I never tried but I don't see a reason for being not feasible.

I got this message now when I tried to run the file. Error # 6476
'DTPL card 2 exists in multiple models with SLAVE data. Design domains
linked through multi-model optimization cannot have SLAVE data.'Any ideas?

Hi @fredriki
This is because duplication of slave IDs and this is already reported and may get fixed in next version of OptiStruct,
As a workaround, you can change the slave DTPL IDs to a different ID and try using the same

Ok, I am trying now to keep Master IDs and changing slave IDs, seems to work but I have a follow up question.
If I define different slave IDs they will all still follow the same Master ID in 3 of my configurations. But in my other 3 configurations, the DV that is master in the 3 previous configurations is not included.
My thought is that I use the same Master ID as I did in the first 3 configurations, but change the coordinate system to the location of where I want the master to be oriented, and use unique slave IDs. This way I should be able to account for the same Master ID in 6 configurations and the rest of the slaves will follow in each configuration.
This should work, right?

I think the master ID is dependent on the design so that should not be a problem,
