How to handle reactive trace substances?
Timo Koch @timok: An idea was that
- Fluidsystem specify numTraceComponents
- sum x_i = 1 (i = main components, excluding trace components)
- x_trace = mass_trace / mass_phase(excluding trace mass)
- Trace compoments get their own advection diffusion equation that is not considered by replaceCompIdx / total mass balance
- Tracer have no influence on molar mass, density, viscosity, ... any other fluid phase property
Would be nice: mechanism to attach a list of tracer to the fluid system at compile time and access it at runtime.
