Nearest nodes

Altair Forum User

how to find nearest node in hypermesh. A command or any macro that should search a tolerance of distance like within radius of 30  and then find nodes within that perimeter . lets say, should find nodes adjacent to it.

Hi

You can select nodes within a sphere

*createmark nodes 1 'by sphere' 

-> i dont remember args so please look up reference help. /emoticons/default_wink.png' srcset='/emoticons/wink@2x.png 2x' title=';)' width='20' />

Hi Sonu,

The API is  *createmark nodes 1 'by sphere' x y z r inside 1 1 .1

hi johnson and tinh

thank you for the answer. was really grateful.

However, I need a little more favour pls.

As you suggested i was able to create a sphere with a central node. however, i want to add those nodes in the form of temporary nodes because as soon as i turn of elements, the nodes dissapear too.

once i have added the nodes, i want to automate it for n number of nodes. how can i run the process in a loop through a tcl.

Hi Sonu,

Once the nodes are displayed using *createmark nodes 1 'by sphere' x y z r inside 1 1 .1 option, you can go to Shift + F2 option and directly add those nodes, so that those nodes will be displayed.

hi johnson, but the problem is, as soon as i turn off the elements, the nodes dissaper too with elements.

Hi

I am not sure what you want to do with the nodes

to mark them as temporary

*createmark nodes 1 'by sphere' x y z r inside 1 1 .1

set NodeList [hm_getmark nodes 1]

*nodemarkaddtempmark 1

foreach NodeId $NodeList {

     # do you job with each node here

}

Is there any code to select the nodes where two components are intersecting? I tried using hm_getnodessharedbyothercomps but the nodes are not selecting.

 

Thank you in advance for any reply

Maybe you have to use command *penetrationcheck
