# Quick List of Combination of Separation Distance amongst Nodes

## Quick List of Combination of Separation Distance amongst Nodes

(OP)
Y'all...

Imagine this:

Collection A    B
of Nodes     Nodes
10001    20001
10002    20002
10003    20003
⋮      ⋮
10123    29876

I desire to get the closest node from 10001 to {20001~29876}
closest from 10002 to {20001~29876}
closest from 10003 to {20001~29876}
etc.

A N D / O R

print out of 'distance' from 10001 to each of {20001~29876}
print out of 'distance' from 10002 to each of {20001~29876}
etc.

Also, Someone on this great forum indicated there exists a function that queries for the proximity of a pair (to many number of) nodes called, feCheckCoincidentNode1 or 2 or 3 or sumsing like zat.

I'm on Femap Build Number: 2301.42
and I can't call this function. Has it disappeared or changed its call name?
Wherez the documentation on the input arguments and stuff related to this family of nodal query function? Is there other functions similar to this type?

As always, Pre-thanks. Nice day.

### RE: Quick List of Combination of Separation Distance amongst Nodes

Dear NASAJPL,
You have a command in FEMAP named MESH > CONNECT > CLOSEST LINK where you select two sets of nodes (FROM and TO), and Femap will automatically generate line elements, constraint equations, or rigid elements between each node in the first set of nodes (Generate From selection) to the nearest node in the second set of nodes (Generate To selection). This is a useful method to automatically generate a series of connections between two patterns of nodes or between a pattern of nodes and a single node.

You can use this command to generate DUMMY 1-d elements, and next list the length of every element and you have the distance that you are searching, tricky!.
Best regards,
Blas.

Hello Mr. Blas Molero.
Your reputable presence in this community is well known by me.
Thank you for enlightening of the feature.
Have yet to try but something tells me, it's going to be a keeper in my bag of tricks.
You wouldn't happen to have a nifty way of listing out the 1D element lengths, would you?
