Detailed Description

template<typename ValueType>
class Bempp::InterpolatedFunction< ValueType >

Function defined by its values at a set of interpolation points and an interpolation method.

Currently the evaluate() method is not implemented. However, VTK-file export (exportToVtk()) works.

Member Function Documentation

template<typename ValueType >

void Bempp::InterpolatedFunction< ValueType >::exportToVtk	(	const char *	dataLabel,
		const char *	fileNamesBase,
		const char *	filesPath = 0,
		VtkWriter::OutputType	type = VtkWriter::ASCII
	)		const

Export the function to a VTK file.

Parameters

[in]	dataLabel	Label used to identify the function in the VTK file.
[in]	fileNamesBase	Base name of the output files. It should not contain any directory part or filename extensions.
[in]	filesPath	Output directory. Can be set to NULL, in which case the files are output in the current directory.
[in]	type	Output type (default: ASCII). See Dune reference manual for more details.

template<typename ValueType >

InterpolatedFunction< ValueType > & Bempp::InterpolatedFunction< ValueType >::operator+=

(

const InterpolatedFunction< ValueType > &

rhs

)

Copy vertex values from a function defined on a subset of the surface of the interpolation grid.

Copy vertex values from a function interpolated on a surface grid.
