Option Definitions
General Simulation Options
DT: 0.005
The time step (in seconds) used by the simulation. This should be small enough that you do not get objects moving through each other or that two objects get so close in a single time step that the reactive force pushes them too far apart.
VISCOSITY: 0.001
The viscosity of the medium. This effects the speed of movement of the bacteria. The force of the bacteria should be selected based on this.
PHYSICS_WELL_WIDTH_BACT_BACT: 0.0 PHYSICS_WELL_DEPTH_BACT_BACT: 0.0 PHYSICS_WELL_WIDTH_BACT_PART: 0.0 PHYSICS_WELL_DEPTH_BACT_PART: 0.0 PHYSICS_WELL_WIDTH_PART_PART: 0.0 PHYSICS_WELL_DEPTH_PART_PART: 0.0 PHYSICS_WELL_WIDTH_PART_BDRY: 0.0 PHYSICS_WELL_DEPTH_PART_BDRY: 0.0 PHYSICS_WELL_WIDTH_BACT_BDRY: 0.0 PHYSICS_WELL_DEPTH_BACT_BDRY: 0.0 PHYSICS_REACT_FORCE: 15.0
All interactions between bacteria, particles and boundaries are handled by a potential function. Each of these options specifies the relevant options for the linear piece-wise function. The same reaction force (when objects overlap) is shared by all objects.
BACTERIA_RADIUS: 0.7
The default radius of a bacterium in microns.
BACTERIA_FORCE_DOWN: 0.41 BACTERIA_FORCE_UP: 0.4387
The force that a bacterium exerts when moving up and down a chemotactic gradient.
UP_RUN_LENGTH: 1.6 DOWN_RUN_LENGTH: 0.7 ISO_RUN_LENGTH: 0.86
The mean run length up and down a chemotatic gradient. Also the run length when in an isotropic region is given. This mean is for the exponential distribution used to model the run length distribution.
PARTICLE_RADIUS: 10.0
The default radius of a particle in microns.
