Some error estimates for the DEC method in the plane (1907.06762v1)
Published 15 Jul 2019 in math.NA and cs.NA
Abstract: We show that the Discrete Exterior Calculus (DEC) method can be cast as the earlier box method for the Poisson problem in the plane. Consequently, error estimates are established, proving that the DEC method is comparable to the Finite Element Method with linear elements. We also discuss some virtues, others than convergence, of the DEC method.
