E4D Electrical Methods Input Files
See File Syntax Rules for specific details.
| Input File | Mesh | Forward | Inverse | Time-lapse | Description |
|---|---|---|---|---|---|
| <e4d.inp> | The run configuration must by named <e4d.inp>. It is the first file read by E4D, and contains the names of input files and other options necessary for E4D to execute a particular run mode. | ||||
| Conductivity | Specifies the conductivity (either real or complex) of each element in the computational mesh. | ||||
| Conductivity list | Specifies multiple conductivity files for a forward run simulation. | ||||
| Mesh configuration | Provides E4D with instructions to build the mesh. The filename must end with a <.cfg> extension. Details and rules describing E4D meshes can be found here. | ||||
| Inversion options | Inversion options for ERT and SIP. Structural metrics and weighting functions, integral to defining inversion options, can be viewed here. | ||||
| Output options | Provides instructions on how to report observed vs. simulated data values, and whether to construct potential files for specified current injection configurations. | ||||
| Survey | Provides the locations of electrodes, describes how electrodes are used to produce measurements, and lists measurement values and standard deviations. | ||||
| Time lapse survey list | Specifires the list of survey files for time-lapse inversion. | ||||
