Dear All,
I prepared a Python script to get initial data from a cae file and modify that for another analysis. To do this, I created a historyOutput command to obtain stress intensity factor and I need to use these values at the post-processing inside of python code, but I have problem with historyRegion definition, could you please give me an advice of why this happen?
Here are the corresponding lines of codes:
#crack tip set
myAssembly.Set(nodes = crackTipNode, name = 'crackTip')
#Contour Integral definitions:
a.engineeringFeatures.ContourIntegral(name='Crack-1', symmetric=OFF, crackFront=crackFront, crackTip=crackTip,
extensionDirectionMethod=Q_VECTORS, qVectors=((v11[7], a.instances['crackedPart'].InterestingPoint(edge=e11[8], rule=MIDDLE)), ),
midNodePosition=0.5, collapsedElementAtTip=NONE)
# Request history output for the crack
myModel.HistoryOutputRequest(name = 'SIF', createStepName = crackStep, contourIntegral = 'Crack-1',numberOfContours = contours,
contourType = K_FACTORS, kFactorDirection = KII0, rebar = EXCLUDE, sectionPoints = DEFAULT)
# Read from history output
crackODB = session.openOdb(name = jobName, path = jobName + '.odb', readOnly = True)
histRegion = crackODB.steps[crackStep].historyRegions['Crack-1']
I put the contourIntegral name for historyRegions, but I get "KeyError: Crack-1" error. I don't what else to do?
Any advice would be really appreciated.
Thanks,
Are you working with a particular custom library for reading these data files?
I'm a little confused. What is the command you're actually running? The error you're getting indicates that you're trying to look up a key that the underlying dictionary does not have.
Dear Morteza,
Thanks for your info, I'm familiar with Stack Overflow website, but just want to see if anyone from RG can help me also.
Dear Boris,
I used 'import odbAccess' in order to access odb library. Actually, the error refers to data set definition, which is a required input for history output request. I did define a set, but it seems I cannot use that one to access the history output.
Solved the problem.
I had to use 'ElementSet . ALL ELEMENTS' instead of 'ElementSet ALL ELEMENTS', in this line:
histRegion = crackODB.steps[crackStep].historyRegions['ElementSet . ALL ELEMENTS']
Only a single '.' changes everything.
