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

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

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

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