DC / IP

In this chapter, we publish code comparisons and validations for direct current resistivity (DC) and induced polarization (IP) modeling packages. In SimPEG the SimPEG.electromagnetics.static.resistivity module is used for modeling DC resistivity data, while the SimPEG.electromagnetics.static.induced_polarization module is used for modeling IP data.
