MODEL COMPUTATION – calculate the apparent resistivity values.The grid lines show the cells for which RES2DMOD will calculate apparent resistivity. The model shows two higher resistivity blocks (light blue) in a matrix of lower resistivity (dark blue). EDIT/Edit Model to see what the model looks like (figure 1).If they don’t they are in the installation directory. From the menu bar in RES2DMOD (bullets indicate individual steps) There are a number of canned models that install with the program. From there, you can change array types, edit the model, change resistivities, or save the model for RES2DINV. RES2DMOD For RES2DMOD, the general sequence is to open a file, calculate the results, and display the model and results. The site also has an excellent tutorial on electrical methods. For both programs, the manuals are detailed and good as are the help documents available from the menu bar this is a short, ‘quick start’, synopsis. The modeling program is available on the web site as is a demo version of the inversion program. The two programs, RES2DMOD and RES2DINV, are from. get a feel for working with electrical resistivity data learn what psuedosections look like for known models experiment with noise and removing noisy observations, and compare Wenner and dipole-dipole arrays. Using RES2DMOD and RES2DINV to Explore Electrical Resistivity Results This is an introduction to resistivity software followed by a few exercises with four objectives: 1.
