Using External Pathways

External Pathways provide a mechanism by which external program modules for contaminant transport (e.g., analytical, finite element or finite difference solute transport models) can be directly integrated into GoldSim. These modules (referred to as External pathway A transport pathway element that provides a mechanism by which external program modules for contaminant transport (e.g., analytical, finite elelement, or finite difference models) can be directly integrated into GoldSim. functions) are linked into GoldSim as DLLs (Dynamic Link Libraries) at run time. External pathways are specialized extensions of the External element.

An example file, ExternalPathway.gsm (and the corresponding DLL) can be found in the Contaminant Transport Examples folder in your GoldSim directory (accessed by selecting File | Open Example... from the main menu). The source code (in C++ and Fortran) for the example can be found in the General Examples/External folder in your GoldSim directory.
