Simulation3DMagneticFluxDensity.Jtvec(m, v, f=None)[source]#

Jvec computes the adjoint of the sensitivity times a vector

J^{⊤} v = ({\frac{d u}{d m}}^{⊤} {\frac{d F}{d u}}^{⊤} + {\frac{\partial F}{\partial m}}^{⊤}) {\frac{d P}{d F}}^{⊤} v

where

{\frac{d u}{d m}}^{⊤} A^{⊤} + {\frac{d A (u)}{d m}}^{⊤} = {\frac{d RHS}{d m}}^{⊤}
