Hi,

I'm doing an analysis of  sloshing with a fuel tank.

The total event time is 0.7 seconds. On time around 0.4 seconds, the run did stop and this follow message appears to me:

 

MESSAGE ID :          174
 ** ERROR : NULL DIAMETER FOR SPH PARTICLE ID=21643
     ERROR TERMINATION

 

I'm using a controller of time-step do run this model.

 

Would somebody help me?

 

Best regards,

    Hi George!

     

    All right! I'm going to try right now!

    As soon as the run finished, I'll  back here to say you what happened.

     

    Thanks a lot!

    But, seeing the 0000.rad and 0001.rad, I noticed that you changed the contac (You used SURF_EXT set, to select the fuel tank and GRNOD set to select the fuel) before i was using the seletion by components. Can you learn me the diference? On 0001.rad i noticed that you removed tha controler time-step by INTER e leaved the controler by NODA. Do you think the controler by INTER caused this error?

    Hi Rickson,

    It seems like the /DT/INTER caused the issue. Run the model and let's review finally.
