A geometric description of Discrete Exterior Calculus for general triangulations

Published 4 Feb 2018 in math.DG | (1802.01158v2)

Abstract: We revisit the theory of Discrete Exterior Calculus (DEC) in 2D for general triangulations, relying only on Vector Calculus and Matrix Algebra. We present DEC numerical solutions of the Poisson equation and compare them against those found using the Finite Element Method with linear elements (FEML).
