Mesh::Tri3::Regular::nelem()
----------------------------
Return number of elements.
Mesh::Tri3::Regular::nnode()
----------------------------
Return number of nodes.
Mesh::Tri3::Regular::nne()
--------------------------
Return number of nodes-per-element (= 3).
Mesh::Tri3::Regular::ndim()
---------------------------
Return number of dimensions (= 2).
Mesh::Tri3::Regular::getElementType()
-------------------------------------
Return element-type. For example used in the :ref:`ParaView` module.
Mesh::Tri3::Regular::coor()
---------------------------
Return nodal coordinates [nnode, ndim].
Mesh::Tri3::Regular::conn()
---------------------------
Return connectivity [nelem, nne].
Mesh::Tri3::Regular::nodesXXXEdge()
-----------------------------------
Node numbers along the "Bottom", "Top", "Left", or "Right" edge.
Mesh::Tri3::Regular::nodesXXXOpenEdge()
---------------------------------------
Node numbers along the "Bottom", "Top", "Left", or "Right" edge, excluding the corners.
Mesh::Tri3::Regular::nodesXXXCorner()
-------------------------------------
Node number of one of the corners (e.g. "BottomLeft").
Mesh::Tri3::Regular::nodesPeriodic()
------------------------------------
Periodic node pairs. Each row contains on pair of (independent, dependent) node numbers. The output shape is thus [n_pairs, 2].
Mesh::Tri3::Regular::nodesOrigin()
----------------------------------
Bottom-left node, used as reference for periodicity.
Mesh::Tri3::Regular::dofs()
---------------------------
DOF-numbers for each component of each node (sequential). The output shape is thus [nnode, ndim].
Mesh::Tri3::Regular::dofsPeriodic()
-----------------------------------
DOF-numbers for each component of each node, for the case that the periodicity if fully eliminated. The output shape is thus [nnode, ndim].
Mesh::Tri3::getOrientation(...)
===============================
Get the orientation (-1 or +1) of all the elements.
Mesh::Tri3::setOrientation(...)
===============================
Set the orientation (-1 or +1) of all the elements.
