Parameter Sweep Undoes Geometry

Please login with a confirmed email address before reporting spam

The below post is related to an archived discussion


I created a geomtry then simulated a few times using EM wave solver in the frequency sweep and the parametric sweep. Then I saved a new version of the file and made an edit to the geometry (added a filet on some edges). I tried to run the parametric sweep again and I get the error that the filet applies to no edges, which it certainly does. In fact, the parametric sweep is undoing my geometry. The variables I am sweeping should not affect the filet in question.

Apparently someone has had this issue before with a parametric sweep undoing geometry. Has anyone else encountered this bug?

Yup. The settings become confused because of the way the software tags/identifies all the many geometric pieces and parts of the model, so when you dynamically change the model, it couldn't figure out any more to what part(s) you intended to apply the filet operation. Remember, it's a computer, not a human. So it's not strictly a "bug." The computer only knows what you tell it, not what you mean. This particular problem doesn't happen to me often, but when it does, I usually just re-assign/re-do my settings or geometry manually to deal with it. But I'm pretty sure there is a better way, quite likely by making smart use of selections. So I suggest you study the use of selections.
