Interpretation of results
After a successful run, nodal stress results at each node of every element should be available in the database. Consequently, multiple results are available at nodes common to two or more elements. These results will not be identical because the finite element method is an approximate method. For example, if a node is common to three elements, there can be 3 slightly different values for every stress component at that node. During result visualization, you may ask for element stresses or nodal stresses.
In calculating nodal stresses at a node, the program averages the corresponding results from all elements contributing to the stresses at that node. For example: In calculating element stresses, the program averages the corresponding nodal stresses for each element. Using the same example:
Important Notes:
• Due to the different methods of averaging, the maximum values obtained from the Element values and Nodal values will be different.
• If your mesh is coarse compared to the rate of variation of results, then the maximum of the element values and the maximum of the node values will be very different.
• Comparing the maximum of the element values and the maximum of the node values will give you an idea of how coarse your mesh is in the maximum stress concentration zone.
