| gun_pos | [float; 3] | Meter | Spawn location of Neutrons. |
| gun_target | [float; 3] | Meter | Fired upon position of new Neutrons. |
| gun_spread | float | degree | Unifrom random spread of Neutrons away from target vector. |
| scat_coeff | float | 1/Meter | Scattering coefficient. |
| abs_coeff | float | Joules/Meter | Absorption coefficient. |
| mins | [float; 3] | Meter | Minimum geometric bound of the target material cube. |
| maxs | [float; 3] | Meter | Maximum geometric bound of the target material cube. |
| num_voxels | [int; 3] | -- | Number of partitions along each Cartesian axis. |
Downloading the release tool should be as simple as:
cargo install neutronsCreate a directory called input, and within it add a parameters file called parameters.json:
mkdir input
touch input/parameters.jsonThe parameters file should look something like this.
You can then run the program with:
neutrons parameters.json
