The Ghost Node Correction (GNC) package is an optional package included in MODFLOW-USG. It can be used to correct errors in the model that are created “when a line between two connected nodes does not bisect the shared face at a right angle”.[1]
GMS provides an interface to the GNC package. The package can be turned on in the MODFLOW Packages dialog, accessible from the MODFLOW Global/Basic Package dialog. The package dialog can be accessed from the main MODFLOW menu or by right-clicking on the MODFLOW item in the Project Explorer.
The user can enter the ghost node data by hand, or allow GMS to compute the data by clicking the Generate Ghost Node Data button. Clicking the button causes GMS to overwrite whatever is in the GncNodes table with the ghost node data calculated using an algorithm based on ghost node locations and distances to adjacent cells.
If the Create points at ghost node locations when generating option is on, GMS will create a new UGrid called "Ghost Nodes" with points located where GMS calculated that ghost nodes should be.
GMS does not currently support some GNC package options, including:
