A novel radial basis function method for 3D linear and nonlinear advection diffusion reaction equations with variable coefficients

Fuzzy transform algorithm based on high-resolution compact discretization for three-dimensional nonlinear elliptic PDEs and convection–diffusion equations

“…Numerical convergence order and solution errors illustrate the close resemblance between approximated and analytic solutions. Fig.5illustrate the sliced contour at 𝑦 = ±1, ±2 of the approximated solution values for 𝐾 =100 in four different layers, appearing parallel to 𝑧-axis.Example 7.5Tian and Lin (2020) Consider the nonlinear elliptic equation…”
