GetNNE

The GetNNE method returns the number of nodes in a specific element of the mesh. This is useful for determining the size of arrays needed for element-based operations.

Interface

INTERFACE
  MODULE FUNCTION GetNNE(obj, globalElement, islocal) RESULT(ans)
    CLASS(AbstractMesh_), INTENT(IN) :: obj
    INTEGER(I4B), INTENT(IN) :: globalElement
    LOGICAL(LGT), OPTIONAL, INTENT(IN) :: islocal
    INTEGER(I4B) :: ans
  END FUNCTION GetNNE
END INTERFACE

Syntax

numNodes = mesh%GetNNE(globalElement, [islocal])

Parameters

Parameter	Type	Intent	Description
obj	CLASS(AbstractMesh_)	IN	The mesh object
globalElement	INTEGER(I4B)	IN	Global or local element number
islocal	LOGICAL(LGT)	IN (optional)	If true, globalElement is treated as a local element number

Return Value

Type	Description
INTEGER(I4B)	Number of nodes in the element

Description

GetNNE returns the number of nodes in a specified element. This is an important property as different element types and orders have different numbers of nodes. The method can be used to allocate arrays of appropriate size for element-based operations.

Example Usage

TYPE(Mesh_) :: mesh
INTEGER(I4B) :: elemNum, numNodes
REAL(DFP), ALLOCATABLE :: nodalValues(:)

! Initialize mesh, elemNum...

! Get the number of nodes in the element
numNodes = mesh%GetNNE(elemNum)

! Allocate an array for nodal values
ALLOCATE (nodalValues(numNodes))

! Use the array for element operations
