I received the error 339 when applying topology optimization using Optistruct.

As it can be seen in the figure i fixed the part at the end of the RBE3s (also at the left end which is not on the figure there are again two fixed ends with rbe3s) and in the middle the load.

Can someone help me with this?

 

Thanks in advance.

    Hi,

    RBE3 with force applied at dependent node => ok

    RBE3 with spc applied at dependent node => failed => change to use RBE2 (or you need a cbush to bind with rbe3, then constraint free end of cbush)
