Free id grid as independent grid in RBE3 data

Altair Forum User

Error coming during compiling an static analysis problem, It is showing:

'Invalid to use free id grid as an independent id grid in RBE3 data.

Free spiders are not allowed to be independent grid in RBE3 data.

                             RBE3 id     =      5527

                         free grid id     =      5959

        weighted components     =        123                                      '

 

How should I correct this error?

Please anyone tell me.

Thanks alot in advance.

Hi Prateek,

 

Independent node should be connected to elements and it should not be free. Please take care of this.
