MapResistivity

class emg3d.maps.MapResistivity

Bases: emg3d.maps._Map

Maps ρ to computational variable σ (conductivity).

• forward: x = ρ = σ^-1
• backward: σ = ρ^-1 = x^-1

Methods Summary

backward(mapped)	Mapping to conductivity.
derivative(gradient, conductivity)	Map derivative from conductivity back to mapping space.
forward(conductivity)	Conductivity to mapping.
