More number of degree of freedoms with double dependency  than the number of independent degree of freedom

Hi, 

 

I checked my optimization setup and got this error: 

 

 *** ERROR # 2933 ***
 There are more number of degree of freedoms with double dependency
 than the number of independent degree of freedom near grid ID
 37283. PARAM,AUTOMSET is ineffective in this situation.
 
 *** Run terminated because of error(s) in the input data.

 

I connected NonDesign Shell Elements to the Solid Designspace vie RBE2 rigids and think that the problem might appear there. 

I do not know what to do to fix this and would be thankful for any help. 

 

Best regards, 

Timo

    you could create a FREEZE contact (or TIE) to merge NonDesign and Design areas, so that you don't need to use RBE2.

    If you're not familiar with those, you might find some tutorials on how to setup contacts in the documentation.

    Hi,

    I also got this error

    Do you have other solutions? 

    Thank you
