E4D Travel-time Input Files
See File Syntax Rules for specific details.
| Input File | Mesh | Forward | Inverse | Description |
|---|---|---|---|---|
| <fmm.inp> | The run configuration must by named <fmm.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. | |||
| 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 travel-time tomography. 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 travel-time files for specified sensor injection configurations. | |||
| Survey | Provides the locations of sensors, describes how sensors are used to produce measurements, and lists measurement values and standard deviations. | |||
| Velocity | Specifies the velocity of each element in the computational mesh. | |||
