Simulation3DMagneticFluxDensity.getRHS(tInd)[source]#

Right-hand sides for the given time index.

This method returns the right-hand sides for the time index provided. The right-hand side for each source is constructed according to:

qk=CMeσ1se,k1Δtk[sm,ksm,k1]

where

  • Δtk is the step length

  • C is the discrete curl operator

  • sm and se are the integrated magnetic and electric source terms, respectively

  • Meσ is the inner-product matrix for conductivities projected to edges

See the Notes section of the doc strings for Simulation3DMagneticFluxDensity for a full description of the formulation.

Parameters:
tIndint

The time index; between [0, n_steps].

Returns:
(n_faces, n_sources) numpy.ndarray

The right-hand sides.
