Sina Jafari is still having a problem:
Thank you very much Bruno and Jan.
The reason why I asked this question is that I want to study fabric evolution
in a granular packing under isotropic loading. To do so, I need to conduct
simulations while keeping them in a quasi-static regime which can only be
achieved by controlling input parameters of my simulation (especially loading
rate and damping). Since I have a large number of spheres in my simulations (
250000 Spheres) and a small time-step, reducing loading rate can lengthen
computation time up to a month as they take 4 days to complete right now with a
loading rate of 0.0002!
I wanted to know that what is the effect of NOT having quasi-static conditions
on simulation results? for example Average coordination number or average
normal contact force? to my mind, such condition can lead to significant
changes in material fabric because contacts are likely to be lost in such
simulation!
