Thank you for the reply! Could you please clarify what you mean by the following statements? 

1). "EKILL will erase the element solution history"

Does this mean that, when an element is set to be alive again, that it will have zero plastic strain?

2). "You should also take care that the elements are sufficiently supported both while killed and after they are reactivated"

Does 'sufficiently supported' mean that each element has enough nearby elements?
