Hi guys, I've done a static analysis of a mechanical component but when I displayed results (VonMises) I've noted this:
21748761.png


at left all elements are in the same component, at right elements are in two different component

at left seems to be continous material while at right seems to be discontinuity... but are the same model!!

I've meshed dragging 2D element on the tue and on the plate, after nodes of solid elements are equivalenced and elements have the same property and mat (only different components: elements of tube in one and the plate in other)

I've analyzed using Nastran and Radioss and the results are the same..
Naturally I thing that the right result is on the left
Where I'd wrong? How it's possible this?

How did you do that?, are you moving elements only from one component to another one? I've done a lot of simulations using different collectors in the same geometry and this result never shows up. See if your elements still connected to the same mesh (you can do it by using the option by attached in the mask tool), or, try to move the elements to a different component and then move it by organizing in other collector.

Regards
