3. NATURE OF PHYSICAL PROBLEM SOLVED

SPIRIT plots the geometry and the results from a 2-D finite elements calculation.

[ top ]

4. METHOD OF SOLUTION

SPIRIT uses the Benson-Lehner graph plotter. The programme will draw each separate element of the mesh according to the description supplied and a complete picture of the mesh is therefore built up. The program can also construct an isothermal distribution using straight lines. Each line is constructed considering each element in isolation.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The program deals only with bodies entirely contained in the first quadrant and the x-coordinates should be less than 20.0.
