A generalized particle tracking and flux-field analysis suite, designed for unstructured model structures and computational scalability.
- the Pollock (1989) method (only works for rectilinear model grids)
- the Waterloo method: a semi-analytic groundwater particle tracking algorithm (Muhammad Ramadhan, 2015)
- Euler and Runge-Kutta pathline integration schemes with adaptive time-stepping
- reads MODFLOW6 output files
- output results to *.vtk for 3D visualizations and animations
- FlowSource volumetric flow tracking (Foley and Black, 2017)
- additional processing:
- Monte Carlo uncertainty analysis
- particle endpoint cluster analysis
more details to come..
