Witryna13 kwi 2024 · This article deals with 2D singularly perturbed parabolic delay differential equations. First, we apply implicit fractional Euler method for discretizing the derivative with respect to time and then we apply upwind finite difference method with bilinear interpolation to the locally one-dimensional problems with space shift. It is proved that … WitrynaIn the examples below, we solve this equation with some common boundary conditions. To proceed, the equation is discretized on a numerical grid containing \(nx\) grid points, and the second-order derivative is computed using the centered second-order accurate finite-difference formula derived in the previous notebook. Without loss of generality, …
