Abstract
Tension spline is a function that, for given partition x0 < x1 < … < xn, on each interval [xi, xi+1] satisfies differential equation (D4 − ρ 2 i D2)u = 0, where ρi's are prescribed nonnegative real numbers. In the literature, tension splines are used in collocation methods applied to two-points singularly perturbed boundary value problems with Dirichlet boundary conditions.
In this paper, we adapt collocation method to solve a time dependent reaction-diffusion problem of the form
with Dirichlet boundary conditions. We tested our method on the time-uniform mesh with Nx × Nt elements. Numerical results show ε-uniformly convergence of the method.
