\section field-space Spatial discretization
A field can be supported by: 
- the nodes (vertices) of the mesh: built with the 
\ref ParaMEDMEM::MEDCouplingFieldDouble::New "ON_NODES" keyword. This is sometimes called a P1 field.
- the cells (or "elements") of the mesh: built with the 
\ref ParaMEDMEM::MEDCouplingFieldDouble::New "ON_CELLS" keyword. This is sometimes called a P0 field.
- or more complex items (Gauss points, etc ...)

\section field-time Temporal discretization

A field has a temporal discretization. It can be one of:
- \ref ParaMEDMEM::MEDCouplingFieldDouble::New "NO_TIME"
- \ref ParaMEDMEM::MEDCouplingFieldDouble::New "ONE_TIME"
- \ref ParaMEDMEM::MEDCouplingFieldDouble::New "CONST_ON_TIME_INTERVAL"
