Using DYNSYSTEM as a complete modeling system has many advantages over other popular groundwater modeling packages. One of the most important is the advantage of a finite-element grid based model.

DYNSYSTEM finite-element grid
MODFLOW finite-difference grid

Some obvious advantages to finite-element triangular gridding is the ability to use greater discretization in important areas while using large elements in unimportant areas. The rectangular, finite-difference gridding system uses many more elements.

Also, you will notice that, in order to create anisotropy within the bedrock system of this model, the MODFLOW grid must be rotated to align the grid with the axis of anisotropy. In the DYNSYSTEM model, anisotropy is created with a simple material assignment, eliminating the need for grid rotation and allowing easy modeling of any anisotropy angle.
