- elem_typeThe type of element from libMesh to generate
C++ Type:MooseEnum
Controllable:No
Description:The type of element from libMesh to generate
- nodal_positionsThe x,y,z positions of the nodes
C++ Type:std::vector<libMesh::Point>
Controllable:No
Description:The x,y,z positions of the nodes
ElementGenerator
Generates individual elements given a list of nodal positions.
Overview
This MeshGenerator object allows the user to create a single element (it is possible to create a simple mesh by adding elements one by one).
The user has to provide the positions of the nodes for their element, as well as the type of element they want (QUAD4, TRI3,...) and the element node connectivity.
commentnote
The reader is referred to the libmesh documentation and doxygen for the conventions on node connectivity in a type of element to create a well formed, positive-volume, non self-intersecting, element.
