In mathematics, a collocation method is a method for the numerical solution of ordinary differential equations, partial differential equations and integral equations. The idea is to choose a finite-dimensional space of candidate solutions (usually polynomials up to a certain degree) and a number of … See more Suppose that the ordinary differential equation $${\displaystyle y'(t)=f(t,y(t)),\quad y(t_{0})=y_{0},}$$ is to be solved over the interval The corresponding … See more In direct collocation method, we are essentially performing variational calculus with the finite-dimensional subspace of piecewise linear functions (as in trapezoidal rule), or cubic functions, or other piecewise polynomial functions. In orthogonal … See more WebBased on the generalized polynomial chaos method, the stochastic Allen-Cahn equation is turned into a set of nonlinear partial differential equations. Then the first-order fully implicit scheme is applied to solve the set of partial differential equations by using the Chebyshev spectral collocation method.
