energyFluxFromNonlinearFlux

converts nonlinear flux into energy flux

---

Declaration

 [Ep,Em,E0] = energyFluxFromNonlinearFlux(Fp,Fm,F0,options)

Parameters

• Fp nonlinear flux into the Ap coefficients
• Fm nonlinear flux into the Am coefficients
• F0 nonlinear flux into the A0 coefficients
• deltaT (optional) include the deltaT term in the Euler time step

Returns

• Ep energy flux into the Ap coefficients
• Em energy flux into the Am coefficients
• E0_A energy flux into the A0 coefficients if three return variables are requested, or returns the kinetic energy flux if four return variables are requested.
• E0_B potential energy flux into the A0 coefficients

Discussion

Multiplies the nonlinear flux (Fp,Fm,F0) by the appropriate coefficients to convert into an energy flux.

Optional parameter deltaT added by Bailey Avila: This equation is C17 in the manuscript, but with addition of 1st term on LHS of C16 converted to energy using Apm_TE_factor or A0_TE_factor This differs from energyFlux due to the importance of the 2FF*deltaT in equation C16 at the initial condition.
