 Allen-Cahn (nonlinear reaction diffusion) Equation 3 reviews The Allen–Cahn equation ( John W. Cahn and Sam Allen) is a nonlinear reaction-diffusion equation of mathematical physics which describes the process of phase separation in iron alloys including...
 A test about discontinuous Galerkin (dG) method for Poisson Equation 1 review Most FEM are absed on the continuous Galerkin (cG) method, a finite element method formulated relative to a weak formulation of a particular model system. Unlike traditional FEM (cG) methods that...
 Convection dominated Convection-Diffusion Equation by upwind discontinuous Galerkin (dG) method 1 review We consider the Convection-Diffusion Equation with very small diffusion coefficient $\mu$: \[ -mu\Delta u + \mathbf{\beta}\dot\nabla u =f \mathrm{in}~ \Omega u=g(x,y) \mathrm{on}~...
 Microsphere resonator 3 reviews This model reproduces the simulation results from: http://dx.doi.org/10.1063/1.4801474 Solutions were stripped so you will have to run the simulation to see the results. That may take a while...
