paraview.simple.LegacyGhostCellsGenerator(*input, **params)

The GhostCellGenerator operates on unstructured grids only. This filter does not redistribute the input data, it only generates ghost cells at processor boundaries by fetching topological and geometrical information of those cells on neighbor ranks. The filter can take advantage of global point ids if they are available - if so it will perform faster, otherwise point coordinates will be exchanged and processed.

Data Descriptors


Specify if the filter must generate the ghost cells only if required by the pipeline downstream. To force at least a fixed level of ghosts, this must be set to 0 (unchecked).


This property provides the name for the input array containing the global point ids if the GlobalIds array of the point data if not set. Default is GlobalNodeIds.


This property specifies the input to the ghost cells generator.


When **BuildIfRequired** if off, use this to specify the minimum number of ghost cells to request. The filter may request more ghost levels than indicated if a downstream filter asked for more ghost levels.


Specify if the filter must take benefit of global point ids if they exist or if point coordinates should be used instead.

Data Descriptors inherited from Proxy


dictionary for instance variables (if defined)


list of weak references to the object (if defined)


Initialize = aInitialize(self, connection=None, update=True)

Methods inherited from SourceProxy


Called when the filename of a source proxy is changed.


Returns the associated cell data information.

GetDataInformation(self, idx=None)

This method returns a DataInformation wrapper around a vtkPVDataInformation


Returns the associated cell data information.


Returns the associated point data information.

UpdatePipeline(self, time=None)

This method updates the server-side VTK pipeline and the associated data information. Make sure to update a source to validate the output meta-data.


This method updates the meta-data of the server-side VTK pipeline and the associated information properties

__getitem__(self, idx)

Given a slice, int or string, returns the corresponding output port

Methods inherited from Proxy

GetProperty(self, name)

Given a property name, returns the property object.

GetPropertyValue(self, name)

Returns a scalar for properties with 1 elements, the property itself for vectors.

InitializeFromProxy(self, aProxy, update=True)

Constructor. Assigns proxy to self.SMProxy, updates the server object as well as register the proxy in _pyproxies dictionary.


Returns a list of all property names on this proxy.

SetPropertyWithName(self, pname, arg)

Generic method for setting the value of a property.


Destructor. Cleans up all observers as well as remove the proxy from the _pyproxies dictionary

__eq__(self, other)

Returns true if the underlying SMProxies are the same.

__getattr__(self, name)

With the exception of a few overloaded methods, returns the SMProxy method


Return hash(self).

__init__(self, **args)

Default constructor. It can be used to initialize properties by passing keyword arguments where the key is the name of the property. In addition registrationGroup and registrationName (optional) can be specified (as keyword arguments) to automatically register the proxy with the proxy manager.


Creates an iterator for the properties.

__ne__(self, other)

Returns false if the underlying SMProxies are the same.

__setattr__(self, name, value)

Implement setattr(self, name, value).

add_attribute(self, name, value)
