test_flume_mhd_riemann_fnl_kernels

Unit test RV-0 (MHD, device half) of the FLUME MHD Riemann solvers: the evaluation routine run on host and device.

Module-level (not a contains-internal procedure): device routines must be module procedures.

Variables

Name	Type	Attributes	Description
NR	integer(kind=I4P)	parameter	Results per pair and direction: nine fluxes, three
IFB1	integer(kind=I4P)	parameter	Result index of the HLLD fallback flag (no divergence control).
IFB2	integer(kind=I4P)	parameter	Result index of the HLLD fallback flag (GLM).
IFB3	integer(kind=I4P)	parameter	Result index of the HLLD fallback flag (EGLM).
GAMMA	real(kind=R8P)	parameter	Specific heats ratio.
CH	real(kind=R8P)	parameter	GLM cleaning speed.

Subroutines

evaluate

Evaluate the nine solvers on one pair of primitive states prim(1:9,1:2) (psi the ninth), direction d; the EGLM states are the GLM ones with psi^2 / 2 added to the energy.

subroutine evaluate(d, prim, res)

Arguments

Name	Type	Intent	Attributes	Description
d	integer(kind=I4P)	in		Direction.
prim	real(kind=R8P)	in		Primitive states of the pair.
res	real(kind=R8P)	out		Results.
