boundaryModesAtWavenumber

Return either the surface or bottom boundary mode at fixed wavenumber.

Declaration 

 psi = boundaryModesAtWavenumber(self,k,isSurface)

Parameters

  • self InternalModesSpectral instance
  • k horizontal wavenumber array
  • isSurface logical flag selecting the surface mode when true and the bottom mode when false

Returns

  • psi requested boundary mode evaluated on zOut

Discussion

This helper estimates the boundary-grid resolution needed to resolve the smallest retained boundary mode, then solves the manuscript SQG-style boundary-value problem spectrally.

          Estimate the grid resolution necessary to resolve the   smallest mode.
