atl_acoustic_2d_physFlux Function

public function atl_acoustic_2d_physFlux(state, acoustic, iDir) result(flux)

Function for physical flux of the acoustic equation F, 1D? Since it is 1d, there need to be passed the correct background velocity (u0 for F - flux in x direction, v0 for G - flux in y direction, w0 for H - flux in z direction)

Arguments

Type	Intent	Optional	Attributes		Name
real(kind=rk),	intent(in)			::	state(acoustic%ndims+1)	State to compute the fluxes (rho, u, v, w)
type(atl_acoustic_type),	intent(in)			::	acoustic	Datatype for acoustic equation include all background data
integer,	intent(in)			::	iDir	Direction of flux, used fot background velocity

Return Value real(kind=rk), (acoustic%ndims+1)

The resulting flux in x direction
