5.2. Forward ModelingΒΆ
Here the code gzfor3d_60.exe is used to forward model the gravity anomaly for the mesh and density contrast model provided. We consider a ground-based survey with a uniform station spacing of 40 m.
Files relevant to this part of the example are in the sub-folder fwd. We used the same model that was created in the create model section. Before running this example, you may want to do the following:
Download and open the zip folder containing the entire grav3d example (if not done already)
Learn how to run gzfor3d
There is no input file
The resulting gravity anomaly (mgal) is shown below. According to the convention used by grav3d, a positive density contrast results in a positive gravity anomaly.
