This program performs forward 2D DC and IP modelling. As command line arguments, it requires fdmesh.dat, potgrid.dat, and model.con for DC forward modelling. An additional argument model.chg is required for IP modelling. An optional argument topo.dat is required when surface topography is present. The program produces a potential data file named `obs.dat', and an apparent chargeability data file named `obs_ip.dat' when IP forward modelling is requested. The names of input files are specified by users but the names of output files are fixed. When topo.dat is supplied, it is used by DCIPF2D to define the topographic surface of the model and the forward modelled apparent conductivities and chargeabilities simulate the data acquired on the topography; otherwise, the program assumes a flat earth's surface at z=0 and carries out the modelling accordingly.

Command line usage:

dcipf2d dc fdmesh.dat potgrid.dat model.con [topo.dat]

dcipf2d ip fdmesh.dat potgrid.dat model.con model.chg [topo.dat]

Input files:

dc|ip
Enter dc to perform only DC forward modelling, or enter ip to perform both DC and IP modelling.
fdmesh.dat
finite difference mesh.
potgrid.dat
electrode locations.
model.con
cell values of a conductivity model.
model.chg
cell values of a chargeability model. Required only if ip is selected.
topo.dat
surface topography (optional).

Output files:

obs.dat
the DC potential data.
obs_ip.dat
the apparent chargeability data.
