Detecting Unconnected rigids

Hi

I'm trying to find a good method to find unconnected rigid elements. (rbe3)

I thought I could find the list of nodes of the rbe3 elements then search through the list of nodes highlighting any that are only attached to one element.

Unfortunately the model with RBE I have as test has a large amount of nodes in its RBEs and is taking 30 mins and counting to search through the nodes.

Is there a faster method that I could be using.

Many thanks

    You're doing that with TCL script?

    The easiest method is go to (press F10) check elems panel > 1D > free 1-d's

    That worked great thanks.

    Also found that in tcl script

       *createmark elems 1 'all'

       *createmark elems 2

       *elementtestfree1d elems 1 2

    Find elements with free nodes and :

        *createmark elems 1 'all'

        *createmark nodes 2

        *elementtestfree1d nodes 1 2

     

    Thanks for your help
