GetNptrs

Inheritence

This method is inherited from the AbstractMesh class.

GetNptrs

The GetNptrs method retrieves the global node numbers present in the mesh. It can return either all node numbers or those belonging to a specific mesh ID.

Interface

INTERFACE
  MODULE FUNCTION GetNptrs1(obj) RESULT(ans)
    CLASS(AbstractMesh_), INTENT(IN) :: obj
    INTEGER(I4B) :: ans(obj%tNodes)
  END FUNCTION GetNptrs1
END INTERFACE

INTERFACE
  MODULE FUNCTION GetNptrs2(obj, meshid) RESULT(ans)
    CLASS(AbstractMesh_), INTENT(IN) :: obj
    INTEGER(I4B), INTENT(IN) :: meshid
    INTEGER(I4B), ALLOCATABLE :: ans(:)
  END FUNCTION GetNptrs2
END INTERFACE

Syntax

! Get all node numbers in the mesh
nodeNumbers = mesh%GetNptrs()

! Get node numbers for a specific mesh ID
nodeNumbers = mesh%GetNptrs(meshid)

Parameters

Parameter	Type	Intent	Description
obj	CLASS(AbstractMesh_)	IN	The mesh object
meshid	INTEGER(I4B)	IN	Mesh ID to filter nodes by

Return Value

Version	Type	Description
Version 1	INTEGER(I4B)(obj%tNodes)	Array of all global node numbers in the mesh
Version 2	INTEGER(I4B), ALLOCATABLE(:)	Array of global node numbers for the specified mesh ID

Description

GetNptrs returns an array of global node numbers present in the mesh. The method has two versions:

1. Return all node numbers in the mesh
2. Return only node numbers that belong to a specific mesh ID

This information is essential for operations that need to iterate over or reference specific nodes in the mesh.

Example Usage

TYPE(Mesh_) :: mesh
INTEGER(I4B) :: allNodes(mesh%GetTotalNodes())
INTEGER(I4B), ALLOCATABLE :: subdomainNodes(:)

! Initialize mesh...

! Get all node numbers
allNodes = mesh%GetNptrs()

! Get node numbers for a specific subdomain
subdomainNodes = mesh%GetNptrs(meshid=2)

PRINT *, "Total nodes:", SIZE(allNodes)
PRINT *, "Subdomain nodes:", SIZE(subdomainNodes)
