3. NATURE OF PHYSICAL PROBLEM SOLVED

The program can assemble different meshes stored on tape or cards. Renumbering is performed in order to keep band width low. Voids and/ or local refinement are possible.
top ]
4. METHOD OF SOLUTION

Topology and geometry are read according to input specifications. Abundant nodes and elements are eliminated.
The new topology and geometry are stored on tape.
