celldiff arguments -n, --diameter : (0.016) diameter of the computation domain (in meters) -c, --maxtime : (100) maximum time (in seconds) to simulate before halting -p, --polymer : (0.3) polymer concentration in [0, 1] -g, --drug : (0.1) drug concentration in [0, 1] -h, --tabletheight : (0.23) height of tablet as a ratio of diameter -r, --releasedfile : filname for exporting release curve. defaults to a timestamped name -s, --statefile : filename for exporting full state data. defaults to a timestamped name -t, --stateperiod : (0) how often to export full state data; 0 == never -d, --compress : (1) perform compression step -e, --seed : (47) random number seed (unsigned integer) -a, --asciiperiod : (1) frame period in iterations for drawing ascii animation -o, --drugdissprob : (1.0) dissolution probability scale for drug -l, --exdissprob : (1.0) dissolution probability scale for excipient -w, --polyshellwidth : (1) width of the polymer shell (calculated in 8-cell, 2x2x2 blocks) -b, --polyshellbalance : (1.0) distribution of polymer in the shell, as an "imbalance factor" -f, --boundarydiffusion : (0.9) exponential decay factor for concentrations in boundary cells -x, --nographics : (1) set >0 to run in non-interactive, text-only mode (suitable for scripting) -u, --drugdiffrate : (0.000001) physical rate of drug diffusion (in m/s2) -k, --exdiffrate : (0.000001) physical rate of excipient diffusion (in m/s2) -y, --cellsize : (0.001) physical size of a cell (in meters) -d, --compress : (1) compression flag the ratio of released drug mass is printed as newline-separated values to the specified file path. the model's state is printed in a multi-column format. rows are separated by newlines, columns by tabs. layout is as follows: first column : cell state as follows: 0 = drug, 1 = excipient, 2 = drug dissolving, 3 = excipient dissolving 4 = fully wetted 5 = polymer 6 = void 7 = boundary (zero concentration) second column : drug concentration third column : excipient concentration example: 64 steps on a side, 1000 iterations, output state every 100 iterations: ./celldiff -n64 -c1000 -t100
