AB - <p style="text-align: justify;">The aim of this paper is to develop the mixed
spectral and pseudospectral methods for nonlinear problems outside a
disc, using Fourier and generalized Laguerre functions. As an
example, we consider a nonlinear strongly damped wave equation. The
mixed spectral and pseudospectral schemes are proposed. The
convergence is proved. Numerical results demonstrate the
 efficiency of this approach.</p>
