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. | 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. The algorithm considers only the horizontal relationship of cells when locating ghost nodes. Thus, if the figure above is considered to be in plan view, the ghost node will be located as shown, but if it is considered to be in a front or side view with a subdivided layer on the right, no ghost node will be created. | ||
If the ''Create points at ghost node locations when generating'' option is on, GMS will create a new [[GMS:UGrid_Module|UGrid]] called "Ghost Nodes" with points located where GMS calculated that ghost nodes should be. | If the ''Create points at ghost node locations when generating'' option is on, GMS will create a new [[GMS:UGrid_Module|UGrid]] called "Ghost Nodes" with points located where GMS calculated that ghost nodes should be. |
