✦ Synopsis

problems still define the solution unknowns at the nodes of the Gauss-Lobatto quadrature, just as in a single domain

We present a new multidomain spectral collocation method that uses a staggered grid for the solution of compressible flow probmethod. Examples include 26, 31], and [3] for general lems. The solution unknowns are defined at the nodes of a Gauss hyperbolic problems and [27] for the Euler gas-dynamics quadrature rule. The fluxes are evaluated at the nodes of a Gauss-

Lobatto rule. The method is conservative, free-stream preserving, equations were presented in 20, 28]. An interesting and exponentially accurate. A significant advantage of the method method for coupled acoustic and elastic wave interactions is that subdomain corners are not included in the approximation, making solutions in complex geometries easier to compute. ᮊ 1996 was proposed in .
