A set of [models and equations] (Brief description of models and equations) can be solved by Notus. There is one subdirectory per each one of them:

`navier`

directory is associated to the Navier-Stokes equations`generic_transport_equation`

directory is associated to the resolution of the transport (advection/diffusion) equation (used to solve the species transport equation system)`energy`

directory is associated to the Energy equation`species_transport`

directory is associated to the set of species transport equations`multiphase`

directory is associated to the set of phase advection equations for multiphase flows of immiscible fluids`turbulence`

directory is associated to turbulence models

Even if this directory is called `modeling`

, it contains some high level numerical methods such as the time uncoupling of the equations and the velocity/pressure coupling method.

There is also a directory to compute the physical properties of the fluid depending on temperature and/or volume fraction, species concentration.

Finally it contains enumerations and scalar variables that are common to all these equations.
