Possible Issues  (1)

ElementMarkers is a function to extract markers from mesh elements. ElementMarker is a symbol used to address these markers in partial differential equations or boundary conditions.

Create a mesh:

Visualize the mesh with markers in the "MeshElements" in blue, the markers in the "BoundaryElements" in red and the markers in the "PointElements" in brown:

Extract the point element markers from the point elements:

Set Dirichlet conditions by using the ElementMarker symbol:
