I would like to use the Paraview.simple python module to load in a vtk time series containing many many files. I will not be able to type in the files one-by-one. Using the python trace shows a command of the form:

tEST_MPScalar_0 = LegacyVTKReader(FileNames=['D:\\TEMP\\MainProblem4\\TEST_001.vtk', 'D:\\TEMP\\MainProblem4\\TEST_002.vtk', 'D:\\TEMP\\MainProblem4\\TEST_003.vtk', 'D:\\TEMP\\MainProblem4\\TEST_004.vtk' ... 'D:\\TEMP\\MainProblem4\\TEST_500.vtk'])

As you can imagine it will be difficult to enter in the file names one-by-one there are over 500. Also I am not importing any other python modules aside from `paraview.simple`.

Does the `LegacyVTKReader()` object have any options that account for having a full time series? I would like to avoid having to generate the list of filenames programmatically. These vary on a case by case basis and it would be difficult to cover all the cases...

Hi awa5114,

Not sure if i understand the problem correct, but the good thing when running Paraview with python scripts is that you can use all the standard syntax for python.

An easy and pragmatic approach to your problem could just be to define a "while loop" and assemble the full string with all the filenames.

file_count = len([f for f in os.walk(".").next()[2] if f[:5] == "TEST_"])
i=1;
list=['D:\\TEMP\\MainProblem4\\TEST_001.vtk']
while i < file_count:
list.insert(i, 'D:\\TEMP\\MainProblem4\\TEST_00' + str(i+1) + '.vtk')
i=i+1;

Hope this will solve your problem, good luck!

Cheers

Thanks for your response. It turns out I am using a method described by a stackexchange response using the glob module: https://stackoverflow.com/questions/...in-a-directory

It turns out the glob module was already pre-installed with paraview. I will use this for now.
