更多信息和选项
- PointElement is used to represent point elements in ElementMesh.
- PointElement can be used as an input to ToElementMesh or ToBoundaryMesh.
- Incidents ik are integers that index an array of spatial coordinates. The coordinate referenced by ek={ik} is the node of the k
point. - A PointElement has always exactly one incident.

Possible Issues (4)
The incidents must be lists of integers:
PointElement[{{a}, {2}}]The number of markers must match the number of incidents:
PointElement[{{1}, {2}}, {1, 1, 2}]Markers must be a vector of integers:
PointElement[{{1}, {2}}, {1, a}]When possible, noninteger markers will be converted to integers:
