Detailed Description

Builds ghost cells for a distributed unstructured grid dataset.

This filter generate ghost cells for distributed a unstructured grid in parallel - using MPI asynchronous communications. The filter can take benefit of the input grid point global ids to perform.

Warning

A step of 'all reduce' (each processor send/receive data to/from all other processors.
The code currently assumes one grid per rank.
PointData and CellData must match across partitions/processes.

Thanks:: This filter has been developed by Joachim Pouderoux, Kitware SAS 2015.

Thanks:: This filter was expanded to compute multiple ghost layers by Boonthanome Nouanesengsy and John Patchett, Los Alamos National Laboratory 2016.

Thanks:

Thanks:: This filter uses different algorithms when obtaining the first layer of ghost cells and getting subsequent layers.

Thanks:

First ghost cell layer algorithm:

each proc obtains surface points using the surface filter
perform an all-to-all to share surface points with each other
for each other proc, look at their points, and see if any points match any of your local points
for each matching point, find all local cells which use those points, and send those cells to that proc. mark the cells that were sent (used for later ghost layers)
receive all cells sent to you, and merge everything together

Thanks:

Subsequent ghost layers

for each cell that was sent last round, find all other local cells which border these cells. 'local cells' also includes all ghost cells which i have. send these cells to the same proc, and mark them as sent last round
receive all cells sent to you, and merge everything together
if another layer is needed, repeat

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkUnstructuredGridAlgorithm.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

virtual void vtkPUnstructuredGridGhostCellsGenerator::SetUseGlobalPointIds ( bool )

virtual

Specify if the filter must take benefit of global point ids if they exist.

If false, point coordinates are used. Default is TRUE.

virtual bool vtkPUnstructuredGridGhostCellsGenerator::GetUseGlobalPointIds ( )

virtual

Specify if the filter must take benefit of global point ids if they exist.

If false, point coordinates are used. Default is TRUE.

virtual void vtkPUnstructuredGridGhostCellsGenerator::UseGlobalPointIdsOn ( )

virtual

Specify if the filter must take benefit of global point ids if they exist.

If false, point coordinates are used. Default is TRUE.

Specify if the filter must take benefit of global point ids if they exist.

If false, point coordinates are used. Default is TRUE.

virtual void vtkPUnstructuredGridGhostCellsGenerator::SetGlobalPointIdsArrayName ( const char * )

virtual

Specify the name of the global point ids data array if the GlobalIds attribute array is not set.

Default is "GlobalNodeIds".

Specify the name of the global point ids data array if the GlobalIds attribute array is not set.

Default is "GlobalNodeIds".

virtual void vtkPUnstructuredGridGhostCellsGenerator::SetHasGlobalCellIds ( bool )

virtual

Specify if the data has global cell ids.

If more than one layer of ghost cells is needed, global cell ids are necessary. If global cell ids are not provided, they will be computed internally. If false, global cell ids will be computed, then deleted afterwards. Default is FALSE.

virtual bool vtkPUnstructuredGridGhostCellsGenerator::GetHasGlobalCellIds ( )

virtual

Specify if the data has global cell ids.

If more than one layer of ghost cells is needed, global cell ids are necessary. If global cell ids are not provided, they will be computed internally. If false, global cell ids will be computed, then deleted afterwards. Default is FALSE.

When BuildIfRequired is false, this can be used to set the minimum number of ghost levels to generate.

Note, if the downstream pipeline requests more ghost levels than the number specified here, then the filter will generate those extra ghost levels as needed. Accepted values are in the interval [1, VTK_INT_MAX].
