Jan Stránský proposed the following answer:
Hi Ning,

The problem is that PyRunner calls functions in global namespace, so
variable self is not defined. I found this workaround - in shear
function do following:

   def shear(self, strain=-1.e-2):
      import __builtin__
      __builtin__.__dict__['saveAddData'] = self.saveAddData
      self.__O.engines=[
         ...
         PyRunner(command='saveAddData()',iterPeriod=500)
      ]

This approach should work. You can also try something with 'global'
statement or globals() dictionary.

Good luck and let us know if it works or not :-)

Jan
