hi guys and gals,
i create this granulometry called C20, my problem is the step time, itś very small and i need to know if there are other form to create it or if i can do any change for obtain better results.

psdSizes=[1.2e-5, 2e-5, 3e-5, 4e-5, 5e-5, 7e-5, 1.6e-4, 2.2e-4, 3.8e-4, 7.5e-4]
psdCumm=[0.0162, 0.0807, 0.1452, 0.2097, 0.3226, 0.3549, 0.4355, 0.5484, 0.7096, 1.]

O.materials.append(FrictMat(young=young,poisson=0.5,frictionAngle=0,density=0,label='walls'))
O.materials.append(FrictMat(young=young,poisson=0.5,frictionAngle=radians(angfric),density=2600,label='sph'))

walls=aabbWalls([mn,mx],thickness=0,material='walls')
wallIds=O.bodies.append(walls)

sph1=pack.SpherePack()
sph1.makeCloud(mn,mx,-1,0,num_spheres,False, 0.95,psdSizes,psdCumm,False,seed=1)
sph1.toSimulation(material='sph')

the time step is the order  1e-12.  what is the limitant parameter ?
regards and thank for time.
