NOTE

1. Different materials can be mixed in the same model.
2. A database of common material properties is included.
3. Element stresses are calculated at the element integration points, where they are most accurate, and extrapolated to the nodes.
4. The difference in element stress values at a node can be plotted to indicate the adequacy of the mesh or they can be averaged to give a unique nodal value.
5. The results of a thermal analysis can be used as input for thermal stress calculations
