Find the edges of hole

Hello Altair Team,

I'm working on a script to find the edges of holes. But I'm unable to find the edges of the hole when a rib is attached to it.

Let me explain it with a picture.

When there is a hole (like a tube hole). I was able to caputure the eges of the hole. As in this picture ( ).

But when I add a rib to the above shown picture to the tube hole, I was not able to read the edges of the same hole. Please refer this picture () for a better unerstanding.

Please guide me to find a way to either create a plot elements around the hole or atleast a way yo retrieve the node IDs of the hole.

Command Used:

*findloops

Thanks in advance.

Regards,

Brahmadev.

Did you try hm_holedetectioninit?

brahmadev

Hi

Did you try hm_holedetectioninit?

Yeah !

Also tried hm_ce_getholes as well as *findholesshell

even they were not working

tinh

Use *findedges

brahmadev

Use *findedges

Isn't there any other option avaiable than this findedge.

Because using the find edges i'm getting problem with the rib edge nodes and also with the flange edge ids

Did you try removing ribs?

brahmadev

Did you try removing ribs?

Yes !

If I remove the ribs it was able to detect the hole edges but not with the ribs (as shown in the above mentioned pictures.)

I even tried with the hm_getedgeloops, still no use....

Are there any other API's that can either detect only the edge of any given component ?

In hm_getedgeloops try not to give any loop type and feature angle

*createmark elems 1 displayed;

'hm_getedgeloops elems markid=1'

When I tried for a similar model with rib it works fine.

Thing is like i may have more than 2 ribs for any given tube hole.

So when there is only 1 rib attached to the hole tube, the above code is working sometimes and sometimes it isn't .
