Singularities and Isolate for Exclusion AutoGEM Controls Last week, a customer was concerned about the singularity warning that Creo Simulate sometimes prints near the end of the summary file.The key phrase of this warning message is “use engineering judgment”. This blog post describes what may happen if you don’t, and along the way discusses some subtle aspects of isolate for exclusion AutoGEM controls.The customer’s model looks like this.Running the analysis results in the following stress results:These results look OK, but the customer was concerned because Simulate warned that the max_stress_vm measure occurred near a singularity. In fact, the high stress is at a singularity, but not at the singularity that Simulate automatically identified. Simulate identifies only certain types of singularities, such as point loads, point constraints and reentrant corners. In these cases, Simulate is very conservative in terms of what measures are identified as occurring near a singularity. Any measure result that occurs within an element t
