3D DC Resistivity Lab: uses and methods
fits a parameterized subsurface resistivity model from DC potential observations.
Applicable scope and calculation boundary
3D finite volume forward modeling; fixed anomaly body geometry, only inverts the two resistivities of background and anomaly body. The closed sides and bottom surface have zero potential, which belongs to the finite box model; an example of synthetic verification using empty data.
model and reference method
∇·(σ∇V) = −Iδ; bounded nonlinear least squares, the data is the transmission resistance ΔV/I.
model version: 1.0.0. The results are used for scientific research, exploration and teaching, please interpret according to the model conditions.
input parameters
- background initial resistivity（Ω·m）
- Value range: 1 – 5000
- Abnormal body initial resistivity（Ω·m）
- Value range: 1 – 5000
- observation transmission resistance (optional)
- JSON array, in A/B/M/N electrode order from the example table; units are Ω. Leave blank to use deterministic synthetic observations.
