control structure

Show us your script please.

If you just say looping 3000 times is so long then answer is looping 3 times only!

Hi Mahes . What do you want to do?

You have a set of nodes need to be updated

You search for adjacent nodes of it

Then if between it and its adjacents existing less than 4 nodes then you add those to the set.

If you perform in 2d model, between each node and its adjacent node, there is nothing! What do you want to do with adjacent nodes?

hi tinh,

I have a model built of both hex and shell elements.

we create some nodal sets.

in those sets from primary nodes I need to fetch the mid nodes and update the set.

This one is a part of my macro.

elements are second order.

2nd line of code mark nodes by sets.

those sets only has primary nodes.

Thanks,

Mahes

I understand

From primary nodes, you want to add to the set only mid nodes nearby them, don't you?

hi tinh,

yes .

final set includes both primary and mid nodes.

is there any other logic other than this.

Thanks,

Mahes

Ok

Do you need to add mid nodes those are inside solid comps? Or only on outer face of solid comps?

hi tinh,

No.

wat I want to do is...

I will do  the mesh the model which has only 1st order elements.

from that I will create nodal sets.

after that I will change all elements to second order.

By running the macro I will update the set which has the midnodes too.

<?xml version="1.0" encoding="UTF-8"?>

<?xml version="1.0" encoding="UTF-8"?>

Ok, look like you want to add only mid nodes on outer face of solid

Can't you switch to 2nd then create sets?

hi tinh,

Usually for me updates for mesh will come often.

each time when I want to edit mesh I have to change it to first order.

So I have do sets again.

Why dont you create set after all updates?

Somehow you should take the least effort of machine and man also

Try arrange your work flow with fewer actions

Hi tinh,

You are correct.This wat we taught.

That's a must thing so have to be done .

/emoticons/default_biggrin.png' srcset='/emoticons/biggrin@2x.png 2x' title=':D' width='20' /> I can write a code that helps to select such mid nodes. But I think if you describe detailly your script aim, I can give another strategy that doesn't need to select mid nodes, shorter and faster,...

hi tinh,

I have done with code using entity info of node id in element edges.

Thanks for the suggestion.

thanks,

mahes
