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

Writer to write unstructured grid in a xml-based vtk data file. Cannot be used for parallel writing.

Data Descriptors


Select the cell data arrays to pass through.


Explicitly choose which arrays to write.


A compression performance parameter from 1 (faster/larger compressed filesize) to 9 (slower/smaller compressed filesize).


The compression algorithm used to compress binary data (appended mode only). None offers fastest write, LZ4 offers fastest compressed write, ZLib offers balanced performance, LZMA offers smallest compressed filesize.


The mode uses for writing the file’s data i.e. ascii, binary, appended binary.


Select the edge data arrays to pass through.


When EncodeAppendedData is turned ON, the writer uses base64 encoding when writing binary data (only if appended mode is selected).


Select the field data arrays to pass through.


The name of the file to be written.


The suffix to append to the file name when writing files at different timesteps. File extensions such as .vtk should be excluded. The % format specifiers are used. For example, _%d will write files as FileName_0, FileName_1, FileName_2, etc., and _%.3d will write files as FileName_000, FileName_001, FileName_002 etc.


Sets the lower bound for timesteps to write.


The input filter/source whose output dataset is to written to the file.


Sets the upper bound for timesteps to write. If less than min, the last time step is used.


Select the point data arrays to pass through.


Select the row data arrays to pass through.


Sets the stride to go through the time steps.


Select the vertex data arrays to pass through.


When writing timesteps, write a supplementary .series json meta file.


When WriteTimeSteps is OFF, the writer writes only the current timestep. Otherwise it is called once for each time step within the min and max range. If those are not set, the writer is called for all time steps available in its input.

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)
