Markus, maybe I should provide a bit more of context: I am working on topology optimization, and the idea is to remove 'void' elements altogether from the analysis. This would imply that the element gets created when the triangulation is created, but it does not contribute to the global stiffness matrix--and importantly, degrees of freedom that completely lie on the 'void' region (i.e. have no connection to 'solid' or 'gray' elements) are also taken out of the stiffness matrix. If in a subsequent iteration of the optimization the element becomes 'gray' or 'solid', then it should be included again in the analysis.
