Functions/Subroutines
program	__m_fftw_fpp_f90__
subroutine	s_initialize_fftw_module ()
	The purpose of this subroutine is to create the fftw plan that will be used in the forward and backward DFTs when applying the Fourier filter in the azimuthal direction.
subroutine	s_apply_fourier_filter (q_cons_vf)
	The purpose of this subroutine is to apply a Fourier low- pass filter to the flow variables in the azimuthal direction to remove the high-frequency content. This alleviates the restrictive CFL condition arising from cells near the axis.
subroutine	s_finalize_fftw_module ()
	The purpose of this subroutine is to destroy the fftw plan that will be used in the forward and backward DFTs when applying the Fourier filter in the azimuthal direction.
