4.2.3. Forward Modeling Program

The forward problem is solved using the executable program e3dmt_fwd.exe. Parameters necessary for running the forward modeling code are set in the input file; denoted here as e3dmtfwd.inp.

4.2.3.1. Running the Program

To run the forward modeling program, open a command line window. Type the path to the code e3dmt_fwd.exe, followed by a space, followed by the path to the input file.

4.2.3.2. Units:

Inputs:

  • Conductivity model: S/m

  • Background susceptibility model: SI

Outputs:

  • MT data: Real and imaginary components of impedance tensor entries (V/A)

  • ZTEM data: Real and imaginary components of transfer function entries (unitless)

4.2.3.3. Output Files

The program e3dmt_fwd.exe creates 2 output files:

  • MT_data.txt: data predicted using the conductivity model provided

  • e3dmt.log: log file
