Catia Composites Geo-Lvl

Catia Composites Geo-Lvl

(OP)
Hey Folks

Can someone explain the Geo-Lvl concept from stack-up files from zones in Catia Composites Design?

I have two screenshots. The spreadsheet shows the stack-up from zones output and the explosion is the output after plies-from-zones. This is easy enough to manipulate by swapping excel rows which moves around the sequences. However, what I've never understood is the Geo-Lvl column. It can't be trying to tell me what Ply 9 is on the same plane as 6.. because it isn't. What are the other options?

Thanks!

RE: Catia Composites Geo-Lvl

Can't find any usefull info in the Google. Try to replace Geo-Lvl for Ply.9 and Ply.6 and see what happens.

so modifying the values either has no effect (it produces the same ply sequence as shown in the explosion) or i get an error stating that the stack up file has been modified (duh) and after clicking ok, it gives the same plies as before

sigh.

but thanks Jenia

Here it is:

This is option is for drop-offs. The Geo-Lvl is the 'relative length' of the ply in the drop-off.

So forget about the stacking sequence. Just imagine a pyramid of plies in a transition zone. The longest ply would have the lowest Geo-Lvl (say 1) and the shortest would have the highest (say 10). And again, you would only see this difference if you had length changes - my example above did not and hence was driving me crazy.

Et voila

Good finding..I'm not too much working with CPE (90% CPM).
