Detailed Description

Base class for vector fields.

This class incapsulates the data and methods needed to store and evaluate a vector field. This is an abstract base class, and the fields associated with a specific field type are implemented as subclasses, for instance 1D, 2D and 3D spline formulations or Lagrange formulations.

Constructor & Destructor Documentation

Fields()

Fields::Fields ( const char *  name = nullptr )

inlineexplicitprotected

The constructor sets the field name.

Parameters

[in]

name

Name of field
