@GregBrown thanks for the explanation link
I like simulation a lot and beat it up all the time. Last year I tried something that shouldn't have worked and I reduced the constraints on my simulation. There are a lot of things turned on in simulation that help you get your analysis work done. Simulation has had some kind of mesh stabilization working because I got answers last year that seemed real. Maybe it was "soft spring" or better "inertia relief". I did a sudo validation by cutting the bracket in half and fixing the cut making the problem into a simple beam problem. The results matched the mesh stabilized results and I had some confidence.
I've always wondered how initial relief stabilized the mesh and I now have a better idea. I'm supposing they use the 1st modal shape to figure out how the part is going to deform and give us a shape. But without material damping, I'm not sure how they predict the magnitude of the shape. It must be some kind of worse case scenario.
I do have a prototype part and I'm validating my analysis as I go. I'm doing a differential analysis allowing me to make changes to the model and determining if the design is getting better or worse. I can easily do this in the computer with confidence.
The prototype was printed and now my molder is bitch'n at me about draft & sink. I've made the changes to the model and want to determine if the bracket is weaker or stronger. This is how I use analysis saving on building prototypes.
Anyway, I need to analyze may design changes now that I've got "inertial relief" dialed in and recommend others do the same.
Great update!
Onshape feels so much faster, was the performance improved when opening large assemblies?
SUPPRESS FROM THIS BOM & CALLOUT HIGHLIGHTING are two useful improvements. Thank you!
How can I ensure that the last layout of the new document page is displayed on a fresh start?
