Anisotropy in 2D Discrete Exterior Calculus
Humberto Esqueda, Rafael Herrera, Salvador Botello +1
We present a local formulation for 2D Discrete Exterior Calculus (DEC) similar to that of the Finite Element Method (FEM), which allows a natural treatment of material heterogeneit…

A geometric description of Discrete Exterior Calculus for general triangulations
Humberto Esqueda, Rafael Herrera, Salvador Botello +1
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 o…
