GMS:DPT Package

Example of the DPT Package dialog

The Dual Porosity Transport (DPT) package is used for solutions to contaminant transportation in a steady state or transient flow field in the immobile domain of the dual porosity system.

The DPT Package dialog is divided into two parts: one on the left which shows the main sections, and one on the right which shows the inputs for the current section.
