User:Mburton/HydroGeoSphere Materials Dialog

HydroGeoSphere's Materials dialog is accessed by right-clicking on the simulation in the Project Explorer and selecting Materials from the menu. The left side of the dialog contains a table with columns for the name, the domain, and the zone. Each domain contains various inputs to define parameters, which appear on the right side of the Materials dialog.
