## 1.1 Cell and Transfer equations

In the TEF, a model is mathematically represented by a set of equations corresponding to two kinds objects:

1. Cells which are elementary models and correspond to evolution equations such as:

   Vector η represent the state variables of cells and the vector φ represent the dependent boundary conditions, i.e. the variables considered as boundary conditions by a cell, but depending upon the complete model state. This dependent boundary conditions are required to make the cells correspond to well-posed problems. These variables are often called state variables, and prognostic variables in meteorology.

2. Transfers which are determined by constraint equations such as:
   These equations are often called algebraic equations, and in meteorology diagnostic equations.
