Structure

Mesh datatype is simply a collection of mesh elements. It is a child of AbstractMesh_.

Deprecated

The support for Mesh has stopped. In future version, the Mesh and FEMesh will be merged. So please use FEMesh instead.

Mesh vs FEMesh

Mesh is a collection of homogeneous elements. All elements in a mesh should be of same type (i.e., triangle, quadrangle, tetrahedron, etc.). For example, we can define a mesh of triangle element or a mesh of tetrahedron element. In contrast, FEMesh is a collection of elements of same dimension. In FEMesh, all elements are either 1D, 2D or 3D. Therefore, FEMesh can contain some elements as triangle and some elements as quadrilateral.
