Hello, everyone As shown in the picture, I add some forces to the model to do the linear static anlysis. I don't want to it move or rotation under that conditions, but the node of the cube can't be fixed in my problem. So I want to fixed the six DOFs in mass center which is the red point in the picture. But the mass center is empty i.e. don't have material and don't have connection with the model. So, the problem is : Is there any method to constrain the six DOFs of mass center and won't effect the result? Can the reb2 element use for solve this problem?(I am a newbie of FEA, I don't familiar with this element) Thank you so much for your time. And any advice will be appreciate. (^_^) Best wishes.
