Select elements from a set of nodes

[vipin 47]

Hi all,

 

Is there any direct api to select elements from a set of nodes?( For example in the image i need the highlighted elements, dont need the adjacent elements to be selected.)

I tried *findmark and *createmark which are selecting the nearby elements too.

Hi Vipin

You can ignore adjacent elems

*createmark nodes 1 {*}$NodeList

*createmark elems 1 "by node" {*}[hm_getmark nodes 1]

*createmark elems 1 reverse

*appendmark elems 1 "by adjacent"

*createmark elems 1 reverse

Another solution you can try is the following:

hm_createmark nodes 1 "by id only" $NodeList;
hm_createmark nodes 1 advanced reverse;
hm_createmark elems 1 "by nodes" [hm_getmark nodes 1];
hm_getmark elems 1;

Nice trick @tinh, @akitoguc 

Works for me!

Just another way to handle this....

 

*createmarkpanel nodes 1 "Select nodes to which the attached elements have to be determined"
eval "*createmark elems 1 \"by nodes\" [hm_getmark nodes 1]"
eval "*createmark nodes 2 \"by elems\" [hm_getmark elems 1]"
*marknotintersection nodes 1 nodes 2
eval "*createmark elems 2 \"by nodes\" [hm_getmark nodes 1]"
*markdifference elems 1 elems 2
set attached_elem_list [hm_getmark elems 1]

Oh, many ways...

@vipin should test which one is the fastest

Using cmd

time {script}

To measure time to finish a script

@tinh

Tested all methods, last one runs faster on bigger assemblies (saves around 5 sec  ).

Thanks again all!
