What is Primary and Derived Variables With The Same Accuracy in Interval Finite Elements about?

This paper addresses the main challenge in interval computations which is to minimize the overestimation in the target quantities. It introduces a new formulation for Interval Finite Element Methods where both primary and derived quantities of interest are included in the original uncertain system as primary variables. The formulation is based on the variational approach and Lagrange multiplier method by imposing certain constraints that allows the Lagrange multipliers themselves to be the derived quantitie
