FLUME — CPU Backend

The CPU backend (flume-cpu) is the MPI (+ optional OpenMP) implementation of FLUME, extending the backend-independent infrastructure of common/.

Status: development (milestones M1 to M13 complete, the list in docs/applications/flume/index.md).

File	Description
adam_flume_cpu.F90	Entry point (program)
adam_flume_cpu_object.F90	flume_cpu_object: ghost update and boundary conditions, WENO residual (with the immersed-boundary variant), Runge-Kutta integration, reflux accumulation and application, output
adam_flume_cpu_<model>[_<solver>]_kernels.F90	One module per physical model (euler, euler_de, euler_ps, euler_de_ps, euler_iso, euler_baro, mhd, mhd_glm, mhd_eglm, mhd_iso, mhd_glm_iso, mhd_baro, mhd_glm_baro) and per Riemann solver of weno-riemann (llf, hll, hllc for Euler, hlld for MHD): the face fluxes of that model, so no kernel branches on the model
adam_flume_cpu_*_kernels_agnostic.INC	The model-agnostic kernel bodies (face, Riemann face, ghost, auxiliary, positivity, MHD) the model modules include
adam_flume_cpu_dissipation_kernels.F90	Viscous, heat-conduction and Ohmic (MHD) face fluxes of order 2 and 4 (issue #65), model-agnostic, added to the inviscid face fluxes before the seam accumulation
