Extending the MODPATH Algorithm to Rectangular Unstructured Grids
1U.S. Geological Survey, 411 National Center, Reston, VA 20192. dwpolloc@usgs.gov.
Abstract:
The recent release of MODFLOW-USG, which allows model grids to have irregular, unstructured connections, requires a modification of the particle-tracking algorithm used by MODPATH. This paper describes a modification of the semi-analytical particle-tracking algorithm used by MODPATH that allows it to be extended to rectangular-based unstructured grids by dividing grid cells with multi-cell face connections into sub-cells. The new method will be incorporated in the next version of MODPATH which is currently under development.
