adam_chase_physics_object

ADAM, CHASE physics class definition, common CPU backend.

Field variables are arranged as follows:

 q(1): r
 q(2): r * u
 q(3): r * v
 q(4): r * w
 q(5): r * E

Field variables fluxes are:

 Fx(1) = r * u       Fy(1) = r * v       Fz(1) = r * w
 Fx(2) = r * u^2 + p Fy(2) = r * u * v   Fz(2) = r * u * w
 Fx(3) = r * v * u   Fy(3) = r * v^2 + p Fz(3) = r * v * w
 Fx(4) = r * w * u   Fy(4) = r * w * v   Fz(4) = r * w^2 + p
 Fx(5) = r * u * H   Fy(5) = r * v * H   Fz(5) = r * w * H

Field auxiliary variables are arranged as follows:

 q_aux(1 ): r  (density)              |
 q_aux(2 ): u  (x velocity component) |
 q_aux(3 ): v  (y velocity component) | primitive variables
 q_aux(4 ): w  (z velocity component) |
 q_aux(5 ): P  (pressure)             |
 q_aux(6 ): T  (temperature)
 q_aux(7 ): E  (total energy)
 q_aux(8 ): H  (total entalpy)
 q_aux(9 ): a  (speed of sound)
 q_aux(10): cv (specific heat at constant volume)
 q_aux(11): Rf (fluid constant, cp-cv)
 q_aux(12): g  (specific heats ratio, cp/cv)

Note that the first nv=5 auxiliary variables are also the primitive ones.
