Detect Edges of n sided holes

[ParticleSkull 109]

Hey guys,

I'm ripping a mesh using the Granular Sheet method but i'm getting these popping holes around the ripped part.
If I use a group + unshared edges i'm able to select all the holes + ripped part.

Does anyone knows a way to select only the holes with an n amount of  sides? Let's say, holes with less than 8 sides only

I would really appreciate any other ideas on how to get rid of the holes. 

 

Thank's
Alvaro

Alright, in fact I realise where's the source of the problem. It was on the Clean node and I just had to uncheck "Remove Degenerate Primitives" and now it's workign fine

Still would like to know how to select the holes though, just by curiosity.

I cannot download your file (.rar) but you can try using a divideSOP with Remove Shared Edges activated, then delete any primitive that has an area above a certain threshold:

in a primitive wrangle:

float measured_area = primintrinsic(0, "measuredarea", @primnum);
if (measured_area > ch("th"))  removeprim(geoself(), @primnum, 1);
