MeshRepresentationBase

class pysit.core.mesh_representation.MeshRepresentationBase(mesh, **kwargs)

Bases: object

Base class for representing an object on a (Cartesian) grid.

This class serves as a base class for physical objects, such as points and planes that model receivers and emitters.

Notes

sampling_operator is always stored as a single row. Thus, the domain grid is flat in ‘C’ ordering. This is so that we can easily stack them into ‘operators’ for cases when there are multiple sources or receivers in a set.

Attributes:

mesh : pysit.Mesh

Physical domain on which the source is defined.

domain : pysit.Domain

Physical domain on which the source is defined.

sampling_operator : scipy.sparse matrix or numpy.ndarray

Linear operator describing how this object is represented on a mesh.

adjoint_sampling_operator : scipy.sparse matrix or numpy.ndarray

The adjoint of the sampling operator.

deltas : list of float

Mesh spacings in each dimension.
