2.2.1. MVIFWD¶
This program performs forward modelling. Command line usage:
mvifwd mesh.msh obs.loc model.fld [topo.dat]
and will create the forward modelled data file mvifwd.mag
.
2.2.1.1. 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.fld
: The magnetic vector components model in X,Y,Z (Cartesian) coordinates.topo.dat
: Surface topography (optional). If omitted, the surface will be treated as being flat and the top of the 3D mesh.
2.2.1.2. Output file¶
The created file is mvifwd.mag
. The file format is that of the data file without the associated standard deviations. The forward modelled data are in nT.
