+
+DESCRIPTION
+ The cngf-pf utility simulates the coupled continuum dynamics of granular
+ deformation and pore pressure. 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).
+
+ -b grain-rate-dependence
+ Granular rate dependence beyond yield [-], (default 0.9377).
+
+ -C fluid-compressibility
+ Fluid adiabatic compressibility [Pa^-1] (default 3.9e-10). Only
+ relevant with fluid dynamics enabled (-F).
+
+ -c grain-cohesion
+ Granular material cohesion [Pa] (default 0).
+
+ -D fluid-diffusivity
+ Fluid diffusion coefficient [m^2/s] (default -1). Overrides
+ fluid permeability (-k), grain compressibility (-P), fluid
+ compressibility (-C), and fluid viscosity (-i). Do not use for
+ transient simulations (-T). Disabled when set to a negative
+ value.
+
+ -d grain-size
+ Granular material representative grain size [m] (default 0.04).
+
+ -e end-time
+ Simulation end time [s] (default 1).
+
+ -F Enable pore-space fluid dynamics.
+
+ -f applied-shear-friction
+ Applied ratio between shear stress and normal stress at the top
+ boundary [-] (default 0.45), overridden by -s and -l if these are
+ set.
+
+ -g gravity-accel
+ Gravity magnitude [m/s^2] (default 9.81).
+
+ -H fluid-pressure-phase
+ Phase of fluid-pressure perturbations [s] (default 0). Only
+ relevant with fluid dynamics enabled (-F).
+
+ -h Show usage information.
+
+ -I file-interval
+ Simulation time interval between writing output to disk [s]
+ (default 1.0).
+
+ -i fluid-viscosity
+ Fluid dynamic viscosity [Pa*s] (1.787e-3). 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. In transient simulations
+ (-T) the permeability value is overridden by the Kozeny-Carman
+ relationship (k = d^2/180 * phi^3 * (1 - phi)).
+
+ -L length
+ Simulation domain length [m] (default 1).
+
+ -l applied-shear-vel-limit
+ Upper limit to modeled shear velocity [m/s] (default nan),
+ overrides -f and -s.
+
+ -m grain-friction
+ Grain friction coefficient [-] (default 0.404026).
+
+ -N Normalize output velocities to the range [0;1].
+
+ -n normal-stress
+ Normal stress applied at the top boundary [Pa] (default 120e3).
+
+ -O fluid-pressure-top
+ Fluid pressure applied at the top boundary [Pa] (default 0).
+ Only relevant with fluid dynamics enabled (-F).
+
+ -o origo
+ Simulation domain origo [m] (default 0).
+
+ -P grain-compressibility
+ Granular material compressibility [Pa^-1] (default 1e-8).
+
+ -p grain-porosity
+ Granular material porosity [-] (default 0.25).
+
+ -q fluid-pressure-freq
+ Frequency of fluid-pressure perturbations [s^-1] (default 1).
+ Only relevant with fluid dynamics enabled (-F).
+
+ -R fluid-density
+ Fluid density [kg/m^3] (default 1000). Only relevant with fluid
+ dynamics enabled (-F).
+
+ -r grain-density
+ Granular material density [kg/m^3] (default 2600).
+
+ -S fluid-pressure-pulse-shape
+ Shape of pulse perturbations in fluid pressure at the top
+ boundary. Valid options are triangular (default) or square.
+ Only relevant with fluid dynamics enabled (-F).
+
+ -s applied-shear-vel
+ Shear the material under constant velocity [m/s] instead of a
+ friction value. 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). Only
+ relevant with fluid dynamics enabled (-F).
+
+ -V bot-vel
+ shear velocity at base [m/s] (default 0).
+
+ -v Show version information.
+
+ -Y max-porosity
+ Granular material porosity [-] at inertia number I=1 in transient
+ simulations (-T) (default 0.55).
+
+ -y min-porosity
+ Minimum granular material porosity [-] in transient simulations
+ (-T) (default 0.20).
+
+ The final simulation state is written to stdout, see OUTPUT FORMAT for a
+ description of the data format.
+
+OUTPUT FORMAT
+ The output consists of the following tab-delimited fields, with one row
+ per cell in the simulation domain:
+
+ 1. position [m]
+ 2. shear velocity [m/s]
+ 3. effective normal stress [Pa]
+ 4. fluid pressure [Pa]
+ 5. friction [-]
+ 6. shear strain rate [-]
+ 7. porosity [-]
+ 8. inertia number [-]
+ 9. shear stress [Pa]
+ 10. cumulative shear displacement [m]
+
+FILES
+ If name is set, the simulation state is written to files in the current
+ directory named in the format <name>.outputDDDDD.txt. Here, DDDDD is a
+ integer counter starting from 00000, and incrementing by 1 for each new
+ file. Each file contains the state at a single point in simulation time.
+ The output format is specified in the section OUTPUT FORMAT, and output
+ files are generated with the interval specified with -I file-interval.
+
