    Hi,

    Sorry for the late reply.

    The “infinite domain” is a test on the actual values of the positions of the nodes. And when there are nodes that go very far (in the galaxy, I mean with coordinate values that tends to +/- infinite), then the sorting time also becomes infinite. And at some point, it is decided to stop with such an error message.

    Please, would you have a chance to look at the animation before this problem occurs. They may have some flying nodes in the destroyed  parts.

    Please, would you check if Idel flag is properly set for this interface?

     

    Hope it helps,

     

    Regards

    Rahul R

    Hello,

     

    I have the same problem with my model. I checked the shell element that is rupturing, the interface definitions, tried different Idel flags but nothing worked.

     

     -- RUPTURE OF SHELL ELEMENT NUMBER      13846

    MESSAGE ID :           87

     ** ERROR : INFINITE DOMAIN DETECTED (I7BUCE)
                IN INTERFACE ID=55

     

    Hope someone can help me out.

    Such an error message may appear during sorting of contact interfaces when the distance between some nodes of the model becomes infinite.

    One has to look at the model behavior to understand why some node coordinates are infinite. One common explanation is 'flying' nodes after rupture of elements belonging to interface surfaces. In this case using Idel =2 in contact interfaces should fix this problem.

     

    If problem still persist, please share your model in the dropbox.

    Hello,

     

    Thanks for the fast support. I tried to use Idel in contact interface, but the problem still shows up. I have put the starter and engine files to your dropbox.

    Hi DonSen,

    Damping is creating issue in this file. 

    Can you recreate the node set for damping and try again?. Try creating the nodes inside of specified contact only for damping and try running the analysis.

    Hello George,

     

    Many thanks to you the model is running now, after recreating the damoing node set.

    Hi ，

         Is this problem solved? 

         I have also encountered the problem.  Could you please   share the solution.

    Hi,

    This error message may appear during sorting of contact interfaces when the distance between some nodes of the model becomes infinite.

    One has to look at the model behavior to understand why some node coordinates are infinite. One common explanation is 'flying' nodes after failure of elements belonging to interface surfaces. In this case using Idel =2 in contact interfaces should fix this problem.

    Please try the same.
