I have created an Abaqus model using the GUI but would like to create node sets using python as it will save lots of time over manually selecting the nodes individually. However, i'm unsure how to write the code for this as I don't know how to reference the model. My code is shown below, it says i have undefined variables ( model and part). These have already been defined in the GUI on Abaqus but unsure how to do that here. Thanks
