HELP! Element deletion from a Lagrangian object.

[mechdrive1]

I am trying to delete the elements from a Lagrangian object using Johnson-Cook damage model by specifying zero energy in the damage evolution option. This Lagrangian object is fed against a stationary Eulerian object (completely constrained). In the result, I can observe elements being removed but there are many elements which are just getting elongated to an unexpected length. I have checked the damage variable output (JCCRT) and its value is reaching 1, however many elements still are present. I am attaching an image of the result.

The bottom workpiece is defined as a rigid body and the feed (translational, rotational) is specified to it. You can think of the Eulerian object as a simple cylindrical object. The mesh used in the top workpiece in which elements are to be deleted is quite fine.

Can anyone please point to where I'm going wrong and where I have to make the correction!?

I've resolved the problem by making two corrections. The first one is requesting 'status' variable and the second one is modifying one of the Johnson-Cook damage model constants. There are no more distorted or otherwise any elements in the path of the tool.
