Maps: Parametrized Block in a LayerΒΆ

Parametrized description of a block confined to a layer in a wholespace. The mapping can be applied in 2D or 3D. Here we show a 2D example.

The model is given by

m = np.r_[
   'value of the background',
   'value in the layer',
   'value in the block',
   'center of the layer (depth)',
   'thickness of the layer',
   'x-center of block',
   'width of the block'
]

def run(plotIt=True):

    mesh = Mesh.TensorMesh([50, 50], x0='CC')  # 2D Tensor Mesh
    mapping = Maps.ParametrizedBlockInLayer(mesh)  # mapping

    m = np.hstack(
        np.r_[
            1.,  # value of the background
            2.,  # value in the layer

        ]
    )

    # apply the mapping to define the physical property on the mesh
    rho = mapping * m
