template<typename inputType >
int	checkEmptyMPIInput (inputType *input)
	This method tests whether the input is a nullptr. If the computation is being done on multiple processes, it is possible that the domain of one process or more is empty, but not others, therefore in that particular case the rest of the filter will not be computed but an error message will not be sent.

Detailed Description

TTK VTK-filter for harmonic field computations.

Author: Pierre Guillou pierr.nosp@m.e.gu.nosp@m.illou.nosp@m.@lip.nosp@m.6.fr

Date: February 2019

The current filter takes a list of sources with attached scalar values and produces a scalar harmonic field fulfilling these constraints.

Parameters

Input0	Input geometry, either 2D or 3D, either regular grid or triangulation (vtkDataSet)
Input1	List of critical point constraints (vtkPointSet)
Output	Output harmonic scalar field (vtkDataSet)

This filter can be used as any other VTK filter (for instance, by using the sequence of calls SetInputData(), Update(), GetOutput()).

See the related ParaView example state files for usage examples within a VTK pipeline.
