The simulation space is one-dimensional + and undergoes confined, simple shear at a pretedermined velocity or + friction ratio. The effective stress is modulated by pore-pressure + dynamics when fluid dynamics are enabled. + + The arguments are as follows: + + -A grain-nonlocal-ampl + Amplitude of granular non-locality [-] (default 0.4). + + -a fluid-pressure-ampl + Amplitude of fluid-pressure perturbations [Pa] (default 0).

Only relevant with + fluid dynamics enabled (-F). + + -j time-step + Override numerical time step length [s]. Only relevant with + fluid dynamics enabled (-F). Outside of stability testing, is + not recommended to specify the time step length manually. + + -K dilatancy-constant + Factor relating dilatancy angle to the volume fraction [-] + (default 4.09). Only relevant with transient granular dynamics + enabled (-T). + + -k fluid-permeability + Darcian intrinsic permeability of granular material [m^2] + (default 1.9e-15). Only relevant with fluid dynamics enabled + (-F), and without transient dynamics.

Overrides -f and is overridden by -l. + + -T Enable transient granular properties. + + -t curr-time + Simulation start time [s] (default 0). + + -U resolution + Numerical resolution of simulation domain [-] (default nan). If + not set, the cell size equals the grain size. + + -u fluid-pulse-time + Time of fluid-pressure pulse peak [s] (default nan).
