- mesh
discretize.base.BaseMesh The mesh on which the discrete set of equations is solved
- f
simpeg.electromagnetic.frequency_domain.fields.FieldsFDEM The solution for the fields defined on the mesh
- du_dm_v
numpy.ndarray The derivative of the fields on the mesh with respect to the model, times a vector.
- v
numpy.ndarray,optional The vector which being multiplied
- adjointbool
If
True, return the ajoint
- src
- Returns:
numpy.ndarrayThe derivative times a vector at the receiver(s)
