! Create arrays to hold node coordinates and stress components Fix the left side, place pressure on top and Solve.

The following set of APDL commands builds and solves the example model seen in the left image in Figure 1, above, and moves its corner node locations and stresses into data array columns: The command *VWRITE can write the coordinate and stress data to ASCII text files for later use. To proceed with the original model, *VGET commands will quickly retrieve node locations and stresses, placing them in arrays. This facility can be used to map stresses from one model to another, when the receiving model fits the same geometry. There is an APDL command called *MOPER that can be used to map those stresses to the locations of another set of coordinates that fit inside and on the boundary of the original set of nodes. Corner Nodes in an FEA AnalysisĪn array of node locations and an array of stress components can be created for corner nodes in an Ansys FEA result. This document explores using APDL commands. There are tools to do this in both Ansys Mechanical APDL, as well as using External Data in Ansys Workbench Mechanical. Users sometimes want to map stresses from one model into another. Note that the *MOPER and /INISTATE commands are essential in carrying out the mapping efficiently.įigure 1: Stresses Mapped from the Left Model into the Right Model This article illustrates how to map stresses in APDL, providing example APDL code to carry out the mapping. There are also ways to do this in the Ansys Workbench environment, using the External Data system. Users can employ APDL commands to map stresses from one Ansys Mechanical APDL model to another, when the two models occupy the same geometry.
