Structure

AbstractNodeField_ is an abstract class which represents the field of nodal variables in finite element method.

AbstractNodeField_ is a child of AbstractField_.

The nodal field is associated with the nodes of a finite element mesh. These variables can be of following types:

  • SCALAR
  • VECTOR
  • SPACE-TIME(ST) SCALAR
  • SPACE-TIME(ST) VECTOR.
