ASTER code

Jerusalem artichoke is classified in the genus Helianthus L., in the family Asteraceae (Aster or Daisy family), in the order Asterales (Table 3.1). Asteraceae is the modem family name, introduced to supersede Compositae under Article 18 of the International Code of Botanical Nomenclature, 1972. Compositae is used in the pre-1972 literature as the family name for Jerusalem artichoke, and it is still acceptable to use it as the family name (in the same way Cruciferae, Gramineae, and Leguminoseae, for instance, are used for the Brassicaceae, Poaceae, and Fabaceae, respectively). 

The model is solved numerically by means of the finite element code ASTER. The equations are discretized within a finite element formulation. The time discretization is implicit and the coupling is solved by means of a global inversion of the system, as explained in Chavant (2(X)1).
