 *  This method determines the type of field to create based on the element type
 *  and the discretization directive. It then determines the number of degrees of freedom
 *  and sets all field parameters (type, nb_compo, nb_ddl, nb_pas_dt,

 *  See the code for the correspondence between directives and
 *  the type of field created.
