AttributeError: 'NoneType' object has no attribute 'label' : What's wrong ? - Etienne17 - Dec-13-2019 Hello everyone, I'm not able to solve my pb by myself, so let me explain what it is. I'd like to automate the calculation with Abaqus. So I begin by creating and writing a script in python and finally I execute this file on Abaqus At the step of my work, I'd like to load a step file on abaqus and not my previous model.cae. But by trying to do this, an error appeared on the following part of my python's file. #LOAD / POINTS a = mdb.models['Verzahnung'].rootAssembly n1 = a.instances['ZR1_instance'].nodes koor_load = (-2.637359,29.302616,3.6) nodes1 = n1.getClosest(coordinates=(koor_load ,)) nodelabel = nodes1[0].label <<<----------------------------- THIS LINE meshnode = n1.sequenceFromLabels((nodelabel,)) a.Set(nodes=meshnode , name='Set-2')ERROR TYPE: AttributeError: 'NoneType' object has no attribute 'label' Just in case, here is the previous code to load the model: mdb = openMdb(r"Model_Stirnrad.cae")And the current code: #OFFNUNG mdb.models.changeKey(fromName='Model-1', toName='Verzahnung') step = mdb.openStep('Model1.stp', scaleFromFile=OFF) mdb.models['Verzahnung'].PartFromGeometryFile(name='ZR_1_K', geometryFile=step, combine=False, dimensionality=THREE_D, type=DEFORMABLE_BODY) p = mdb.models['Verzahnung'].parts['ZR_1_K'] a = mdb.models['Verzahnung'].rootAssembly a.Instance(name='ZR1_instance', part=p, dependent=ON)Hope this is clear :D And thanks to those who are enough courageous to read my pb and solve it :) Have a nice WE. RE: AttributeError: 'NoneType' object has no attribute 'label' : What's wrong ? - ibreeden - Dec-13-2019 Verzeihung, it is not clear. From the code it seems n1.getClosest is a class. And this class is expected to have a method or an attribute called label . But it appears not to have such.It is even questionable whether "n1.getClosest" is a class because the message says: " 'NoneType' object". So you should search how "n1.getClosest" is defined. |
