How to modify the rolling resistance
Asked by
Zhicheng Gao
I want to generate a dense sand assembly. Considering the particle shape and the residual strength in the triaxial test, I need to set the rolling resistance. But if I want to get a dense sand specimen, I need to set the rolling resistance and friction angle to a very small value first, and in the deviatoric compression process, I need to modify the rolling resistance and friction angle to the calibration value. How to do that? I only know that the friction angle can be modified by setContactFriction.
