+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]. | |

+ Fluid pressure applied at the top boundary [Pa] (default 0). | |
+ Only relevant with fluid dynamics enabled (-F). | |
+ | |
+ -o origo | |

+ | |
+ -p grain-porosity | |
+ Granular material porosity [-] (default 0.25). | |
+ | |

+ 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). | |
+ | |

+ Shear the material under constant velocity [m/s] instead of a | |
+ friction value. Overrides -f and is overridden by -l. | |
+ | |

+ 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). | |
+ | |

+ | |
+ -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. | |
