analysis of 3D sector of piston
2 Attachment(s)
How can we analyse sector of a 3D piston in star cd , without creating 2d template.. I mean how can we analyse a piston with tangential holes into the compression chamber..I have provided an image for the same....when i created the spline , i didn't get a proper spline..both images are provided..

kindly help :) :)

If you are still looking for an answer. For the es-ice sector tool, it has to have rotational symmetry.

I don't know what you can try to fix your issue.
but I am curious about that hole :) could you explain me shortly what the purpose of that hole is if it is not confidential?

maybe a link for an article etc.

thank you.

Hi Cnaksoy, that was also on my mind. I would think the hole would increase soot and probably also undermine the swirl in the first place.
