FEA questions

[CAD-One]

Hi Guys,

Few questions related to this stress analysis.

1. Why is the mesh size less dense on one part?

2. I know we can use local mesh, but can we use different mesh size on different parts?

3. How can I know on which part is the max stress label pointing/attched to? Since the 2 parts are made of different material I want to know which one is highly stressed in this application.

1. The mesh controls are functions of the part size.  If you have a part who's longest dimension is 100unit  and an average element size of 0.2, your mesh elements are on the order of 20 units.  If you have another part in the assembly that is 10 units long, the same mesh setting will generate elements 2 units long.

2. In IV 2014, it looks like you have to grab faces or edges of components to modify the mesh.  I don't see a way to set mesh controls by part.  I have not checked in IV 2015.

3. I don't see a way to get that information direclty, but you should be able to hide components in your results.  That will let you use process of elemination until you find the component with maximum stress.  I usually just zoom into the view until I can see the arrowhead.

Thanks  lot for explaining about the mesh density and the asnwers for the other 2. Appriciate it.
