PointElement

PointElement[{{i₁},…,{i_n}}]

represents n point elements e_k with incidents {i_k}.

PointElement[{e₁,…,e_n},{m₁,…,m_n}]

represents n point elements e_k and n integer markers m_k.

Details and Options

PointElement is used to represent point elements in ElementMesh.
PointElement can be used as an input to ToElementMesh or ToBoundaryMesh.
Incidents i_k are integers that index an array of spatial coordinates. The coordinate referenced by e_k={i_k} is the node of the k point.
A PointElement has always exactly one incident.

Create a PointElement with two points:

The incidents must be lists of integers:

The number of markers must match the number of incidents:

Markers must be a vector of integers:

When possible, noninteger markers will be converted to integers:
