In this technique the weighted averaging is done by calculating area apportioned to the nodes, and multiplied with the corresponding stress values for those nodes, and then summed up, and then we divide that sum by total area of nodes. Note: The surface chosen to do the averaging is defined as named selection ‘Face_01’ (used in the macro). The contents of the command object can be downloaded here. The weighted area average nodal stress on the surface is reported under the details of the command (in the red circle below) with the parameter named “my_ave_stress1”. This can be done by implementing the macro in a command object as shown. Technique 1 : Reporting weighted area average nodal stress – “Average” stresses on a volume (based on elements) – “Average” stresses on a face (based on elements) – “Average” stresses on a face (based on nodes) There are tricks to do this either for a group of nodes/elements on a face or elements within a specific volume.ĭepending on the requirement, the goal may be to simply report either : Occasionally it may be a requirement to report average values of stress or strain from an ANSYS Mechanical analysis.
