Find closest node and paste it to a fixed node in tcl

Altair Forum User

Hi everybody,

 

I have a question regarding how to find the closest node to a specific temp node and than paste to this specific node by usage of a tcl script?

Which command do I need to use?

 

thanks in advance

Hi,

you can use hm_getclosestnode

Hi tinh,

 

thanks for your Support.

I tried to use the command hm_getclosestnode:

 

Temp Node Id = 97 (x=0; y=10; z=12.913)

 

I tried to find the closest node like this:

hm_getclosestnode 0 10 12.913 0 0

 

Is this correct? If yes, what am I doing wrong, because HM said the closest node is the node with ID 97...

But this is my temp node...

In my opinion HM should have Show node ID 34 as closest node (see Picture attached)...

Of course, hm is correct because your temp node (97) is closer to (0,10,12.9) than 34

to find out the node #34 you have to ignore #97:

*createmark nodes 1 97

set node34 [hm_getclosestnode 0 10 12.9 0 1]

Hi tinh,

 

yes that's true!

Actually I tried without the temp node, because I dont need the temp node at all. All I need are the coordinates and those I have.

 

Thank you very much for your support - greetings from Germany!
