If you've run your FEA analysis in Ansys Workbench, and you're using fe-safe 6.5 there is an fe-safe component for Ansys Workbench if you are going to run the model with the same settings for all the elements. However for Verity you need to set fatigue algorithms differently for different groups in the model, and this require analysis in a standalone version of fe-safe instead of using the component.  After the verity job has been run, you can still do your fe-safe post-processing in Ansys Workbench using the Mechanical viewer you're used to using. 

This requires you duplicate your Static Structural (or Thermal) system that was used to create the original stress results. Duplication will create twice the Ansys workbench project size, so a nice simple solution is to create a downstream system which shares the mesh of the original solution, with a trivial FEA solution. Then the instructions to Clear Generated Data on the downstream system can be used to Import FEA Results as discussed in Appendix H of the fe-safe Appendices. Find an example of how this is done using fe-safe 6.5 and Ansys Workbench 16 in the video above.
