![]() ![]() Though, when a requirement that “the stress must nowhere exceed 70% of the yield stress” has been stated, this may still turn out to be an issue. Experienced analysts know when stress peaks are an expected effect of modeling and can be safely ignored. ![]() In my previous role as a structural analysis consultant, I sometimes came across the problem of how to report ridiculously high stress peaks in a finite element model to a customer. While most of this discussion is in terms of structural mechanics, similar phenomena can also be found in many other physics fields. ![]() In this blog post, we will explore the common causes of singularities, when and how to remove them, and how to interpret results when singularities are present in your model. iFeature extraction process can be tricky and confusing at times.Your finite element model will sometimes contain singularities - that is, points where some aspect of the solution tends toward an infinite value. Regardless, this Derive -> Combine approach extends the type of supporting geometry greatly (unlike iFeature). You will need to apply threads to the holes afterwards. One drawback with this approach is the ability to create spec holes. Lastly use Combine -> Cut to create the holes. Use Direct Edit -> Body -> Move to relocate the tool to the desirable location. Then when you need to drill the holes, just derive the tool part as a separate solid body. Think of these holes being drilled by tools. Please note that the features to be extracted should not have local dependency on geometry that is not part of the extracting features (origin geometry or other edges).Īnother workflow I personally think can be helpful is to create tool parts. Then insert it to a part when geometric conditions are satisfied. You can extract the Hole features as an iFeature. ![]()
