This document presents a finite element formulation using Finite Calculus (FIC) for solving convective-diffusive problems with sharp gradients. FIC modifies the governing equations by including characteristic length distances, which helps stabilize solutions. The FIC method is implemented by solving the modified governing equations using the Galerkin finite element method. Characteristic length vectors are computed based on principal curvature directions of the solution. Numerical examples demonstrate that FIC provides more accurate solutions than standard SUPG by better resolving sharp gradients.
