An adjoint approach for uncertainty quantification of magnetoquasistatic field problems

We discuss an adjoint approach for error control adjusted for a stochastic collocation method. The method is used for uncertainty quantification of low-frequency electromagnetic problems governed by the magnetoquasistatic equations. The error can be estimated by applying a collocation method of the same polynomial degree to both the primal and the adjoint field problem. The performance of the error estimator is illustrated by a numerical example.
