A multidomain pseudospectral method, which is based on Chebyshev polynomials expansions, is presented to solve an initial-boundary value problem in incompressible MHD, the tearing instability, in which a boundary layer is spontaneously generated inside the spatial domain. The method is based on a property of Chebyshev pseudospectral expansions which accurately describe functions having strong gradients localized near one of the Chebyshev domain boundaries.
