Based on a new DIY concept for software development,an automatic program-generating technology attached ona software system called as Finite Element Program Generator(FEPG)provides a platform of developing pro-grams,through which a scientific researcher can submit his special physico-mathematical problem to the systemin a more direct and convenient way for solution.For solving flow and heat problems by using finite elementmethod,the stabilization technologies and fraction-step methods are adopted to overcome the numerical difficul-ties caused mainly due to the dominated convection.A couple of benchmark problems are given in this paper asexamples to illustrate the usage and the superiority of the automatic program generation technique,including theflow in a lid-driven cavity,the starting flow in a circular pipe,the natural convection in a square cavity,and theflow past a circular cylinder,etc.They are also shown as the verification of the algorithms.
