>What does the literature suggest how to handle this situation? > The literature says, I cite: "The nodes that lie inside the void and whose nodal support is not intersected by the void are removed from the calculations. This is performed usually by removing the DOFs associated with those nodes from the system of equations and solving the system only for the remaining DOFs." The question is how to realise it with dealii tools by constrainment of zero degrees of freedom?

Enrichment function does the job in this case. I showed an example of such a coarse mesh in the picture beneath.
