How to define and get results (stresses) for certain points of a model in abaqus, using python? When the size of the model changes?

I want to do a parameter study of a aixsymmetric cylinder in Abaqus. I want to create several jobs where I get the stresses for 3 different points in my model. These points are defined. I wrote a...
