-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 fricâ
- tion 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 comâ
- pressibility (-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 relâ
- evant with fluid dynamics enabled (-F).
-
- -h Show usage information.
-
- -I file-interval
- Simulation time interval between writing output to disk [s] (deâ
- fault 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 [-] (deâ
- fault 4.09). Only relevant with transient granular dynamics enâ
- abled (-T).
-
- -k fluid-permeability
- Darcian intrinsic permeability of granular material [m^2] (deâ
- fault 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 relaâ
- tionship (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), overâ
- rides -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).

- 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 boundâ
- ary. 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 releâ
- vant with fluid dynamics enabled (-F).

- 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.
