	)		const

overridevirtual

Redefinition of fluxes from parent.

Given 1d position x and time, determine analytic solution of Euler conserved variables.

Parameters

q	(input, unused)
aux	(auxiliary vars, unused)
pSV	solverVariables_t pointer contains position x and time
result	(output vars, writing to this)

Reimplemented from WmApplication.

◆ setup()

void wxm::apps::five_moment::Euler1D_Riemann_Problem_Analytic_Solution::setup ( const WxCryptSet & wxc )

overridevirtual

Determine all states and wave speeds given initial pritimive variable left and right conditions for the Riemann Problem.

This is an implementation of the solution described in sections 14.11 and 14.12 of "Finite Volume Methods for Hyperbolic Problems" by Randall J. Leveque, 2002.

Note: Input and Aux vars are not used as the analytic solution is directly calculated.

Parameters

WxCryptSet wxc which should contain GAS_GAMMA, "LeftPrimitiveState", RightPrimitiveState", and "Fluid" variables that are being calculated as ouput.

Reimplemented from WmApplication.
