Electrical Methods Run Modes
E4D executes according to a run mode chosen by the user. Workflows for run modes can be classified generally as mesh generation, forward modeling, inverse modeling, and time-lapse inverse modeling. Required input files, and the formats of those files, vary somewhat depending on the run mode.
| Run Mode | Workflow | Description | Former Designation |

| ERT1 | Mesh Generation | Mesh generation for electrical resistivity modeling and inversion | 1 |
| ERT2 | Forward Modeling | Direct current potential field and electrical resistivity survey simulation | 2 |
| ERT3 | Inverse Modeling | Electrical resistivity inversion for a single survey | 3 |
| ERT4 | Time-lapse Inverse Modeling | Electrical resistivity inversion for multiple time-lapse surveys | 4 |
| SIP1 | Mesh Generation | Mesh generation for spectral induced polarization modeling and inversion | 21 |
| SIP2 | Forward Modeling | Complex potential field and spectral induced polarization survey simulation | 22 |
