RBE3 Elements with different weight factors

Hello,

 

I am working on a model in hypermesh where the loads are applied at a single dependent node and transferred to multiple independent nodes. I would like the RBE3 weighting factor to change between groups of nodes. Can I assign different weighting factors to different independent nodes in a single RBE3 element? If not, how can I apply my loads?

 

I have tried using multiple RBE3 elements (one for each weighting factor) except I get the following error (Node 189285 is the node where the loads are applied)

 

*** ERROR # 173 ***
A dependent d.o.f. defined more than once in rigid element entry.
GRID ID =   189285
component =        1

 

Thanks,

Malcolm

    Hello,

     

    For this you need to go to the update subpanel in the RBE3 panel. This will let you assign weight factors to the slave nodes.

    Please find more information on this in the Help Pages
