A Chebyshev Pseudospectral Method For Numerical Simulation Of The The chebyshev pseudospectral method for optimal control problems is based on chebyshev polynomials of the first kind. it is part of the larger theory of pseudospectral optimal control, a term coined by ross. [1]. The main objective of this paper is to develop an efficient numerical method for the solution of a two dimensional incompressible viscous fluid with internal recirculating flows generated inside a bounded geometry.
Frequency Contents Of The Mapped Chebyshev Pseudospectral Method For Pseudospectral methods are based on discrete function approximations that allow exact interpolation at so called collocation points. the most prominent examples are the fourier method based on trigonometric basis functions and the chebyshev method based on chebyshev polynomials. In this method, the solution is represented as a sum of basis functions (e.g., chebyshev or fourier polynomials), and the collocation points are used to enforce the equation's constraints. For this purpose, the numerical simulation of incompressible navier stokes equations in two dimensions (inse2d) is based upon a chebyshev collocation spectral method (also named chebyshev pseudospectral method) in conjunction with a projection method. In this study, a hybrid chebyshev pseudo spectral finite difference time domain (cps fdtd) algorithm is proposed for simulating 2d acoustic wave propagation in heterogeneous media, which is different from the other traditional numerical schemes such as finite element and finite difference.

The chebyshev pseudospectral method is a numerical method that uses collocation points to ensure that the solution to a problem satisfies the governing equations exactly. We present a new pseudospectral method for two dimensional magnetization and transport current superconducting strip problems with an arbitrary current voltage relation, spatially inhomogeneous strips, and strips in a nonuniform applied field. the method is based on the bivariate expansions in chebyshev polynomials and hermite functions.
