ParaView has a built in Python interpreter that allows for operations done in ParaView to be automated.
Extract surface using paraview, the code will look like
from paraview.simple import * #========== read in data file print 'Read phasta file' dataObj = PhastaReader( FileName= 'restart_one.pht' ) # you have to change the name of this pht file SRF = ExtractSurface(Input=dataObj) MGBLK1 = MergeBlocks(Input=SRF) vtkWriter = DataSetWriter(FileName = 'Surface.vtk' , Input = MGBLK1, FileType = 1) # you have to change the name of this vtk file vtkWriter.UpdatePipeline()
Get the python file from

Generating Python Scripts for Data Extraction
Generating python scripts can be done in the Paraview GUI and is actually pretty easy and straightforward. This process is documented here in an example. Once the the script you want is generated, that script can be edited to automate data extraction. Again, a general example of this is outlined here. Finally, once the script is run, data will be exported and look something like this.
Examples
You can find examples of advanced uses for the ParaView scripting in the utilities repository. Specifically, the general/ParaView_* directories.
