Julian,
you can use the properties subdomain_id() or material_id() to mark cells
that are inside or outside the 'solid' region.
Best,

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.

Hello Julian,
could you please describe in more detail, what you mean by
"removed from analysis"? What do you want to do?
Best Regards,
Markus

Thanks!
