Leonard posted a new comment: Hi William, >However, the unbalanced force is nan and the mean stress is 0 all the time whlie I modfy this using your code. The reason I think is that: you modify only the young from 5e6 to 29e9, while in triax=TriaxialStressController( maxMultiplier=1.+2e4/young, # spheres growing factor (fast growth) finalMaxMultiplier=1.+2e3/young, # spheres growing factor (slow growth) thickness = 0, stressMask = 7, internalCompaction=True, # If true the confining pressure is generated by growing particles ) The radii expansion multiplier is associated with the young value in my MWE, which means you set it very small when you change young very high. Actually, the particles are growing but very slowly, so that you didn't observe any contacts between particles and hence there is no unb and mean stress. If you wait enough time (could be very long), you may observe the unb and mean stress increase. You may play with the parameters in the TriaxialStressController, for example, using a fixed value of maxMultiplier.
