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]
