HI all,
I'm a postgraduate student and I'm writing my master thesis at the Warwick
University.
I'm studying the sand behaviour in Simple-shear test by changing the strain
rate.
In order to evaluate the stress in different points of the periodic cell I want
to use the module:
yade._eudoxos.InteractionLocator.macroArountPt
So I wrote: " from yade import eudoxos" at the beginning of the script.
and then:
.....
def saveData():
strain=strainTensor() # strain tensor
stress=stressTensor() # stress tensor
#
-------------------------------------------------------------------------
# STRESS TENSOR, normal and tangential component
sigN,sigT=utils.normalShearStressTensors(compressionPositive=True)
sigN,sigT=sigN.diagonal(),sigT.diagonal();
#
-------------------------------------------------------------------------
# STRESS TENSOR - NORMAL PART - strong and weak component
stressStrong,stressWeak=utils.normalShearStressTensors(compressionPositive=True,splitNormalTensor=True)
stressStrong,stressWeak=stressStrong.diagonal(),stressWeak.diagonal()
#
-------------------------------------------------------------------------
# FABRIC TENSOR, strong and weak component
fabStrong,fabWeak=utils.fabricTensor(splitTensor=True,revertSign=True)
fabStrong,fabWeak=fabStrong.diagonal(),fabWeak.diagonal()
#
-------------------------------------------------------------------------
# FABRIC TENSOR, total
fabTot=utils.fabricTensor(splitTensor=False)[0] # get the matrix (the
function returns a tuple)
fabTot=fabTot.diagonal()
#
-------------------------------------------------------------------------
pointstress=_eudoxos.InteractionLocator.macroAroundPt((0.00001,0.00001,0.00001),0.00001,[-1])
......
But I get the following:
NameError Traceback (most recent call last)
/usr/lib/yade-daily/py/yade/__init__.pyc in <module>()
----> 1

--> 130
pointstress=_eudoxos.InteractionLocator.macroAroundPt((0.00001,0.00001,0.00001),0.00001,[-1])
131
132 # ENERGY TERMS
NameError: global name '_eudoxos' is not defined
Any ideas why it doesn't work?
Thanks in advance,
Giuseppe
