[Paraview] Writing csv data in python script (UNCLASSIFIED)

[Su, Simon M CTR USARMY ARL (US)]

Caveats: NONE

Hi Casey,

On a somewhat related topic,

>>> s = Sphere()
>>> sum = 2 + 1
>>> w = DataSetCSVWriter(s, FileName='/tmp/test.csv', 
>>> FieldAssociation='Points')
>>> w.UpdatePipeline()

If I want to just write the value of variable sum to a csv file, how would 
that be done?

Thanks
-simon

I tried this in the binary download of paraview 4.1



>>> s = Sphere()

>>> w = DataSetCSVWriter(s, FileName='/tmp/test.csv', 
>>> FieldAssociation='Points')

>>> w.UpdatePipeline()

>>>



and successfully had a file written.

You might try explicitly passing your reader as input to the DataSetCSVWriter 
rather than relying on the active source.

I am not familiar with partitioned unstructured grid to know if any additional 
steps are needed.


good luck

	Hi Casey,


	I get no error and I read my data with XMLPartitionedUnstructuredGridReader.

		Do you get any error messages in the python console or output window?


		What type of data does your source produce polydata, unstructured grid, etc?

			Hi Casey,

			I've tried this like in your suggestion:

			SetActiveSource(IntegrateVariables1)
			DataSetCSVWriter()
			FileName="foo_points.csv"
			FieldAssociation = "Points"
			UpdatePipeline()


			and other similar commands but none produced a csv file. Any hints?

			Thanks

on lines 468-476 for how this is done in VeloView.  You can ignore the 
rotateCSVFile function call.

					Hi,

					>>> writer.UpdatePipeline()
					>>> del writer

					But I get:
					Traceback (most recent call last):

					AttributeError: 'str' object has no attribute 'UpdatePipeline'


					Thanks for any help.
