VolumeModel

class emg3d.models.VolumeModel(grid, model, sfield)

Bases: object

Return a volume-averaged version of provided model.

Takes a Model instance and returns the volume averaged values. This is used by the solver internally.

\[\eta_{\{x,y,z\}} = -V\mathrm{i}\omega\mu_0 \left(\rho^{-1}_{\{x,y,z\}} + \mathrm{i}\omega\varepsilon\right)\]

\[\zeta = V\mu_\mathrm{r}^{-1}\]

Parameters:

grid : TensorMesh

Grid on which to apply model.

model : Model

Model to transform to volume-averaged values.

sfield : SourceField

A VolumeModel is frequency-dependent. The frequency-information is taken from the provided source filed.
