Jan Stránský proposed the following answer:
Hello,

> It seems that I can just get one VTK file.
> TW.defToVtk("strain.vtk")

you specified only one file name, so you get only one file.
Have a look at [2] for an idea how to save multiple files. Will need some modification for PyRunner, something like:
###
class TWExporter:
   def __init__(self,base):
      self.base = base
      self.i = 0
   def export(self):
      TW.setState(1)
      TW.defToVtk("strain_{:03d}.vtk".format(self.i))
      self.i += 1
twExporter = TWExporter("strain")

O.engines = [
...
PyRunner(...,command="twExporter.export()"),
]
###

cheers
Jan
