Error 16946 Pathsweep1 unable to perfrom sweep

Shan25_22239

In the attched model I am trying to sweep a ellipse along a path defined by 'Union1'. I get this error message. I get the same error message in FEKO 19 and 2022. Could you please help to resolve this issue.

Hi Torben,

Thanks for oking into it. The fittedspline technique was working for most of the cases. I will try to avoid the self-intersecting points in the curve.

Thanks

Hello,

I believe you can only do a path sweep along a wire/edge component. You won't be able to select the path that is a union, you will need to separate it and perform the sweep along the primitive wire before the union. I hope this helps!

Hi @Shan25_22239,

What you could try is to create a FittedSpline using Snapping along the desired line. That would result in one single path. But I saw that the line is self-intersecting at one point, which most likely will not work with Path Sweep.

Best regards,

Hi,

I did a quick test with Feko 2022 legacy by creating a fitted spline and then using it as path. It is crucial how tight the curves are in the fitted spline and how big the radius of the disk is. In the attached model, I halved the radius of the disk to make it work. If you want the radius to be larger, the curves of the fitted spline must be less tight.

I marked examples for tight curves along the path.

Thanks Torben! I require the wire radius to to 2 mm, hence I have modified the shape generation code to avoid sharpe turns. Thanks for your time lokking into it!
