4.2.1. GZFOR3D¶
This program performs forward modelling. Command line usage:
gzfor3d mesh.msh obs.loc model.den [topo.dat]
and will create the forward modelled data file gzfor3d.grv
.
4.2.1.1. Input files¶
All files are in ASCII text format - they can be read with any text editor. Input files can have any name the user specifies. Details for the format of each file can be found in Section [Elements]. The files associated with are:
mesh.msh
: The 3D mesh.obs.loc
: The observation locations.model.den
: The density contrast model in g/cc.topo.dat
: Surface topography (optional). If omitted, the surface will be treated as being flat and the top of the 3D mesh.
4.2.1.2. Output file¶
The created file is gzfor3d.grv
. The file format is that of the data file without the associated standard deviations. The forward modelled data are in mGal.
