expand_grid_model
(model, expand, interface)[source]¶ Expand model and grid according to provided parameters.
Expand the grid and corresponding model in positive z-direction from the edge of the grid to the interface with property
expand[0]
, and a 100 m thick layer above the interface with propertyexpand[1]
.The provided properties are taken as isotropic (as is the case in water and air);
mu_r
andepsilon_r
are expanded with ones, if necessary.The
interface
is usually the sea-surface, andexpand
is therefore[property_sea, property_air]
.- Parameters
- modelModel
The model; a
emg3d.models.Model
instance.- expandlist
The two properties below and above the interface:
[below_interface, above_interface]
.- interfacefloat
Interface between the two properties in
expand
.
- Returns
- exp_gridTensorMesh
Expanded grid; a
emg3d.meshes.TensorMesh
instance.- exp_modelModel
The expanded model; a
emg3d.models.Model
instance.
