ceguo is still having a problem:
Hi Bruno,

Thanks for your reply.
-To encapsulate a simulation and call from python, I use the module `yadeimport` adapted from `yade-trunk`. Actually it is provided by Jan. My previous solution is copying all the libraries to the python lib directory properly, which also works smoothly. Here I show how to use yadeimport:

=====================================================
from yadeimport import *
from yade.wrapper import *
from yade import pack

class simDEM(object):
    def __init__(self,sd=1):
        self.__id='thread'+str(sd)
        self.__O=Omega()
        self.__O.materials.append(FrictMat(young=1e9,poisson=1.,frictionAngle=.3,density=2650))
        self.__sp=pack.SpherePack()
        self.__sp.makeCloud(minCorner=(0,0,0),maxCorner=(20,20,0),rRelFuzz=.5,num=2000,periodic=True,porosity=0.28,seed=sd)
        self.__sp.toSimulation()
        self.__O.cell.hSize=utils.Matrix3(20,0,0, 0,20,0, 0,0,1)
        for p in self.__O.bodies:
            p.state.blockedDOFs='zXY'
        self.__O.dt=.5*utils.PWaveTimeStep()

    def consolidate(self,stress=(-2.e6,-2.e6,0,0,0,0)):
        ...

    def finalize(self):
        self.__O.exitNoBacktrace()

For `yadeimport`, I can send to anyone interested in this method (Jan
sent to me). This method is useful for coupled problems as in my case I
coupled yade with another FEM code.

-As my test is very time-consuming, I usually run during night. So I
didn't monitor the RAM usage. Just when I came back in the morning, I
saw the error message.
