PointElement

PointElement[{{i1},,{in}}]

represents n point elements ek with incidents {ik}.

PointElement[{e1,,en},{m1,,mn}]

represents n point elements ek and n integer markers mk.

Details

  • 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^(th) point.
  • A PointElement has always exactly one incident.

Possible Issues  (4)

The incidents must be lists of integers:
