Inversion Workspace

 

To enter the forward modeling workspace:

- press the toobar button
or
-  choose File > New Project > Survey Design from the main menu.

Forward modeling is used to test hypotheses and design electrode layouts and array schedules (quadrapole lists) that best address a specific project. The basic steps for forward modeling are:

1. Create an  electrode  layout and  generate a  sequence
2. Import the electrodes and sequence into the Forward model workspace
3. Design a mesh
4. Create a halfspace model
5. Run the halfspace forward model
6. Create a model with a target embedded in the halfspace
7. Run the target forward model
8. Compare the data values for each quadrapole to determine sensitivity relative to instrument noise.
9. Revise electrode layout and sequences and repeat steps 1 through 8 until suitable sensitivity is achieved.


The forward workspace consists of the Configuration settings, data input, Run controls, Save results, Mesh parameters and Progress info (message area). The explorer screen provides access to sub-menus that provide graphical input for selected configuration settings. Run forward solver may be selected at any time after a schedule has been input. Parameters are automatically chosen by the software. These are overwritten as each configuration setting is changed either directly on the screen shown, or when following the menus on the explorer screen. Please follow the links provided for a description of each sub-menu. To create a schedule for forward modeling, complete with  electrode location information, it may be best to start at with the ERTLab Sequencer.
