Gosh that’s weird. I don’t understand how these things can happen, you can add features but you can’t delete them properly afterwards? I guess there is a reason to do with the intersecting rounds, I’ll take richmars’ advice and not use rounding ’till the last steps. Another friend of mine was grumbling about using SE as a preprocessor, maybe it’s just not good for this?
Any tips about where I can learn more about how to do it better in the future?
For the other Rich:
He’s saying the model is full of faults or discontinuities.
FEA is simplification of a solid object model [which contains effectively an infinite number of bonds and connections between molecules] to a finite number of connections with known behaviour [f=kx etc]. This allows Finite number of elements to be analysed, a simulation run to determine the behaviour the connections between them, and thus derive a useful model of the behaviour of the object subjected to loads.
Basically, computer structural analysis of a solid model.
Breaks/gaps, or self-intersecting surfaces will cause problems with the analysis, and because I’ve added blended rounds to the right-angle edges, and then deleted them, it’s buggered up.
