Function Documentation

ShallowWater1DRoeAverage()

int ShallowWater1DRoeAverage	(	double *	uavg,
		double *	uL,
		double *	uR,
		void *	p
	)

Compute the Roe-averaged state for the 1D shallow water equations. This function just calls the macro _ShallowWater1DRoeAverage_ and is not used by any functions within the 1D shallow water module. However, it's necessary to define it and provide it to the the solver object (HyPar) so that it can then send it to interpolation functions for a characteristic-based reconstruction.

Parameters

uavg	The computed Roe-averaged state
uL	Left state (conserved variables)
uR	Right state (conserved variables)
p	Object of type ShallowWater1D with physics-related variables
