4.3.2. Forward Modeling

The program ggfor3d.exe performs the 3D forward modelling of gravity gradiometry data for a density contrast model defined on a tensor mesh.

4.3.2.1. Running the Program

To run the executable, open a command window. In order, enter the path to the ggfor3d executable, the tensor mesh file, the survey file, the density contrast model file and a topography file (optional). This in shown below.

4.3.2.2. Units

  • Data: gravity gradiometry in Eotvos

  • Model: density contrast model in g/cc

4.3.2.3. Output Files

The program ggfor3d.exe creates the following output files:

  • ggfor3d.gg: Predicted data file.

  • ggfor3d.log: Log file which provides details about the parameters used in the forward modelling and diagnostic information about the results.
