In a first paper [1], the authors have developed the key features of a
n object-oriented environment for the symbolic derivation of linear in
itial-boundary-value problems. The approach was illustrated on a simpl
e example of an elastic bar in dynamics. In a companion paper [2], the
structure of the proposed environment was described at length. In thi
s article. the key features of the automatic generation of finite elem
ents in a symbolic object-oriented environment are given. A few exampl
es of derivation and automatic programming are developed and numerical
ly tested. First, a classical Galerkin formulation of Stoves flow is c
ompared to a Galerkin least-squares stabilization formulation. Then, v
arious stabilized formulations are tested on a simple scalar diffusion
model equation.
