Abstract : We present a new multidomain spectral collocation method that uses staggered grids for the solution of compressible flow problems. The solution unknowns are defined at the nodes of a Gauss quadrature rule. The fluxes are evaluated at the nodes of a GaussLobatto rule. The method is conservative freestream preserving and exponentially accurate. A significant advantage of the method is that subdomain corners are not included in the approximation. making solutions in complex geometries easier to compute. (AN)
