Volume of a set of elements in ODB?

[DrBwts]

So I tried to use the following,

for g in range(1, 3):

    # Extract element volumes from ODB
    odbName = 'TopLoad_Gen_' + str(g) + '.odb'
    odb = session.openOdb(odbName)
    lastFrame = odb.steps['Step-1'].frames[-1]
    volumeField = lastFrame.fieldOutputs['EVOL']
    nucleus = odb.rootAssembly.instances['SPHEREINBOX-1'].elementSets['CENTRESPHERE']
    volumeSet = volumeField.getSubset(region=nucleus, elementType='C3D10')
    volumeFieldValues = volumeSet.values

    volume = 0
    for vol in volumeFieldValues:
        volume += vol

    print volume
    session.odbs[odbName].close()

I'm using Abaqus 6.14 & apparently 'EVOL' no longer exists as a field output. Surely there is a method to extract this basic piece of info?

I tried it manually & looked at the .rpy file but not method was listed just the messages telling me what I had done.

EVOL (Current Element Volume) is a field output. If you check the Users Guide there are some exceptions:

Standard:
Not available for eigenfrequency extraction, eigenvalue buckling prediction, complex eigenfrequency extraction, or linear dynamics procedures. Available only for continuum and structural elements not using general beam or shell section definitions.

Explicit:
Only available for continuum and structural elements not using general beam or shell section definitions.

I'm using second Standard & order tets (C3D10) in a structural loading problem, so there shouldn't be a problem right?

 

[Dave442]

Shouldn't be any problem. Did you request EVOL as a field output?

 

[DrBwts]

Ahhh yes good catch, I was just assuming it would be in with the defaults.

Thanks

I've done this so many times. Glad you got sorted.
