2D DC Resistivity Lab: uses and methods
fits a parameterized subsurface resistivity model from DC potential observations.
Applicable scope and calculation boundary
2D finite volume forward modeling; fixes the anomaly body geometry and only inverts the two resistivities of the background and the 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.
