Fluid Aspect Course 2.2.7: Fluid Objects

MonoFluid: holds the state of one fluid constituent (GUNNS_O2, etc) in a PolyFluid
PolyFluid: has one MonoFluid for each constituent in the network, holds the state of the mixture

Every fluid node has 2 PolyFluids:

mInflow: represents the mixed state of all flows coming into the node.
- Only used as a temporary mixing place for inflows before it is added to the mContent.
mContent: represents the state of the contents in the node’s volume.
- The fluid states in mContent are balanced at the end of the network frame. Once balanced, their state is consistent with the network solution (except for state error).

All links have a pointer to a PolyFluid called mInternalFluid that is dynamically allocated to an actual PolyFluid object, but only when that link class needs it.
- This pointer can be NULL.
- This fluid is used by some links that modify the fluid passing through it.
Some links add more PolyFluid objects to track other fluid states separately.
- All of these link fluids are generally only for temporary use by the link and don’t represent balanced states that are consistent with the network solution.
- Keep this in mind when looking at these fluid states.
