I wish to do an impact analysis of the CRPF tube, I was just not able to understand how to do it in RADIOSS.

I have used Hypermesh - Optistruct and I know about properties like PCOMP, PCOMPP. But I'm not sure what model setup should I use in RADIOSS.

    Hi,

     

    Similar to PCOMPP there is PROP type 17 and 19 for stack and ply, in RADIOSS. 

     

    Please check the same if you want to use ply based modeling in RADIOSS.

    HI,

     

    The RADIOSS FAQ has the following information about that error.

    What is the meaning of: 'Infinite domain detected'?

    This message can be written by RADIOSS Engine.

    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 the failure of elements belonging to interface surfaces. 

     

    You may have to play with the velocity and also check the material properties of the tube.
