Detailed Description

template<int dim>
class Functions::CutOffFunctionW1< dim >

Cut-off function for an arbitrary ball. This function is a cone with support in a ball of certain radius around center. The maximum value is 1. If vector valued, it can be restricted to a single component.

Constructor & Destructor Documentation

◆ CutOffFunctionW1()

template<int dim>
Functions::CutOffFunctionW1< dim >::CutOffFunctionW1 ( const double  radius = 1.,
const Point< dim >  p = Point<dim>(),
const unsigned int  n_components = 1,
const unsigned int  select = CutOffFunctionBase<dim>::no_component,
const bool  integrate_to_one = false 
)

Constructor. Arguments are the center of the ball and its radius.

If an argument select is given, the cut-off function will be non-zero for this component only.
