Distance between two nodes

Altair Forum User

Hello,

I need to access the distance between two nodes using a tcl file.

How can I do it ?

Thanks

Hi Benoit,

 

you can use the command hm_getdistance to do that

Hello Toan,

Thanks for your help.

Hi

It is hm command

Replace ( and ) and , by space to get tcl commands

 

If you are searching for closest node on surf, use hm_measureshortestdistance, do not use loops which will slow down program

Hello

When I use the command hm_getdistance HyperMesh returns 4 values and I need to put the fist one in a variable distance.

(Documents) 4 % hm_getdistance nodes 3723 5317 0 0
68.91864249631689 41.6426000000006 54.90046920132 -1.2694999999999936

How can I isolate the first value in a variable?

thanks

Hi Benoit,

For what you want, you need to use TCL command: lindex.

this command is used to return the element from a list.

Try the following code.

Cheers

 set distance_list [hm_getdistance nodes 3723 5317 0]. set distance [lindex $distance_list 0]
