GetConnectivity

Inheritence

This method is inherited from the AbstractMesh class.

GetConnectivity

This function returns the global node numbers that define the connectivity of a given element. By default, it returns the vertex connectivity, but you can use the opt parameter to request different types of connectivity (edge, face, cell, or all).

Interface

MODULE PURE FUNCTION getConnectivity(obj, globalElement) RESULT(ans)
  CLASS(Mesh_), INTENT(IN) :: obj
  INTEGER(I4B), INTENT(IN) :: globalElement
  INTEGER(I4B), ALLOCATABLE :: ans(:)
END FUNCTION getConnectivity

Purpose

Retrieves the connectivity information for a specified element in the mesh.

Syntax

connectivity = mesh%GetConnectivity(globalElement, islocal, opt)

Arguments

• globalElement (INTEGER, input): The global (or local) element number to retrieve connectivity information for.
• islocal (LOGICAL, optional, input): If present and true, then globalElement is treated as a local element number. Default is false.
• opt (CHARACTER, optional, input): Specifies which type of connectivity to retrieve.
  • "V" or "Vertex" - Vertex connectivity (default)
  • "E" or "Edge" - Edge connectivity
  • "F" or "Face" - Face connectivity
  • "C" or "Cell" - Cell connectivity
  • "A" or "All" - All connectivity types

Returns

• connectivity (INTEGER array): A 1D array containing the global node numbers that define the specified element's connectivity.

Example

INTEGER(I4B), ALLOCATABLE :: vertexConn(:)
! Get vertex connectivity for element 5
vertexConn = mesh%GetConnectivity(5)

! Get edge connectivity for element 10
INTEGER(I4B), ALLOCATABLE :: edgeConn(:)
edgeConn = mesh%GetConnectivity(10, opt="E")
