nonlinearFluxWithMask

returns the flux of each coefficient as determined by the nonlinear flux

---

Declaration

 [Fp,Fm,F0] = nonlinearFluxWithMask(mask)

Parameters

• mask mask applied to all constituents

Returns

• Fp flux into the Ap coefficients
• Fm flux into the Am coefficients
• F0 flux into the A0 coefficients

Discussion

operation and the given mask.

The mask is applied to the coefficients Ap,Am,A0 before computing the nonlinear flux. This is useful for zeroing wavenumbers at given total wavenumber or frequency, for example.

The nonlinear flux used is the unforced, invicid equations.
