Mesh

class cee.usg.Mesh()

A mesh defines the surface elements and nodes for a Part in a Geometry

A mesh is defined by a node array with x,y,z values and the element nodes describing the index of the nodes in each element. The number of nodes per element is defined by either a singleElementType for meshes where all the elements have the same number of nodes or by an array (elementTypeArr) with one item per element describing the number of nodes in that element.

Mesh is an immutable class, so if you need to change something you will have to construct a new mesh.

Methods


Constructors

constructor

cee.usg.Mesh.constructor(nodeArr, singleElementType, elementNodeIndexArr, optionalData)

Create a mesh.

Arguments
  • nodeArr (ArrayLike[number]) –

  • singleElementType (number) –

  • elementNodeIndexArr (ArrayLike[number]) –

  • optionalData (cee.usg.OptionalMeshData) –

Return type

cee.usg.Mesh

For mesh with only one element type (all elements have the same number of element nodes) use the singleElementType version. This is more compact for storage.

The nodeArr is an array of all the nodes in the mesh as an array with [x0, y0, z0, x1, y1, z1, …].

If you have a varying number of element nodes in your elements, specify that with an array (elementTypeArr) with one item per element specifying the number of nodes for that element.

cee.usg.Mesh.constructor(nodeArr, elementTypeArr, elementNodeIndexArr, optionalData)

Create a mesh.

Arguments
  • nodeArr (ArrayLike[number]) –

  • elementTypeArr (ArrayLike[number]) –

  • elementNodeIndexArr (ArrayLike[number]) –

  • optionalData (cee.usg.OptionalMeshData) –

Return type

Accessors

cee.usg.Mesh.elementCount

The number of elements in the mesh.

cee.usg.Mesh.elementNodeIndexArray

Returns an array containing the node indices for each element node in the mesh.

cee.usg.Mesh.elementTypeArray

If not single element type, this array contains the number of elements for all elements in the mesh

cee.usg.Mesh.nodeArray

A readonly array containing the nodes of the mesh

cee.usg.Mesh.nodeCount

The number of nodes in the mesh.

cee.usg.Mesh.singleElementType

Returns the number of nodes in each element if all elements in the mesh have the same number of nodes

Returns 0 if there are multiple element types.

Methods

getBoundingBox

cee.usg.Mesh.getBoundingBox()

Returns the BoundingBox of the mesh.

Return type

cee.BoundingBox
