Prepare and solve the Navier-Stokes equations.

Routines relative to the phase advection equations (multiphase flows).

Poisson equation
It discretizes and solves the Poisson equation.

Species transport equations
It prepares and solves the species transport (or advection/diffusion) equations.

## Detailed Description

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.
