Hi Armin,

That is correct. I only observe this behavior with what I have circled in the image. If I set the "enmass" entry to 1 (" eroding nodes of solid elements are retained and continue to be active in contact.") is that more realistic here?

I am a bit confused as to how the erosion criteria really works? For instance, when an element has been determined to erode it seems to be fully removed from the calculation, but is the mass redistributed to other nodes to conserve mass? Also, when a element erodes, the next neighbor exposed element will meet the surface and cause another stress wave to propagate which is not physical (to my understanding). Any insight here is appreciated.
