Hi,

 

I am working on bird strike analysis by using Radioss.  I received following Warning message.

What can I do to overcome this warning ?

Any suggestions ?

    Hi,

     

    I don't use RADIOSS (LS-Dyna user) but it sounds like a contact search failure (bucket search) and RADIOSS switch to quadratic search.

    Normaly it is only a warning and not a problem (maybe lose of speed).

     

    You can try to redefine contact areas, maybe some more and smaller.

     

    Best regards,

    Mario

    Hi Mario,

     

    I tried to run the model by redifining the contact its showing the same warning as mentioned below and not giving any results also.

     

    ** WARNING ** BUCKET FAILED, QUADRATIC SEARCH.
      ** WARNING SPH SEARCH FOR NEIGHBOURS & SPH COMPUTATION.
      ** INFO ** SPH RE-SEARCH FOR NEIGHBOURS

     

    Any suggestions ?

    Hi everybody

     

    Have you find out the reason of the warning message?

     

    I have the same problem in a woody sphere water entry....and can't find out how to overcome the warning.

     

    i'm using Radioss block 120

     

    best regards
