Detailed Description

This implicit function mollifies on implicit function using another implicit function (e.g., "GaussianSphereIF"). Basically, the IF being mollified is sampled in a small (specified) neighborhood of a point and convolved with the mollifying function in this neighborhood.

Constructor & Destructor Documentation

◆ MollifyIF() [1/3]

MollifyIF::MollifyIF ( const BaseIF a_impFunc,
const BaseIF a_mollifier,
const Real a_min,
const Real a_max,
const int &  a_numPts 

Constructor specifying the implicit function to mollify (a_impFunc), the mollifier (a_mollifier), a neighorhood to use (a_min, a_max) is each dimension, and a sampling (a_numPts).

◆ MollifyIF() [2/3]

MollifyIF::MollifyIF ( const MollifyIF a_inputIF)

Member Function Documentation

◆ value() [1/2]

virtual Real MollifyIF::value ( const RealVect a_point) const

Return the value of the function at a_point.

Implements BaseIF.

◆ value() [2/2]

virtual Real MollifyIF::value ( const IndexTM< Real, GLOBALDIM > &  a_point) const

Return the value of the function at a_point.

Reimplemented from BaseIF.

◆ newImplicitFunction()

virtual BaseIF* MollifyIF::newImplicitFunction ( ) const

Return a newly allocated derived class. The responsibility for deleting the memory is left to the calling function.
