Nodal Coordinate

[peyman1358]

Hi all,

Can I have an output file (made by recorder) from opensees that contains only nodal information as follows:

Node number- X,Y and Z coordinate of nodes


Thanks
Peyman

here is what frank has about the print command:

Print Command
From OpenSeesWiki
Jump to: navigation, search
This command is used to print output.

To print all objects of the domain:

print <$fileName>


To print node information:




print <$fileName> -node <-flag $flag> <$node1 $node2 ...>


To print element information:




print <$fileName> -ele <-flag $flag> <$ele1 $ele2 ...>





--------------------------------------------------------------------------------
$fileName (optional) name of file to which data will be sent. overwrites existing file. default is to print to stderr)
$flag integer flag to be sent to the print() method, depending on the node and element type (optional)
$node1 $node2 .. (optional) integer tags of nodes to be printed. default is to print all.
$ele1 $ele2 .. (optional) integer tags of elements to be printed. default is to print all.

EXAMPLE:

print -ele; # print all elemenmts

print -node 1 2 3; # print data for nodes 1,2 & 3

Thank you Silvia

I used the print command and it wrks but what I exactly need is a file which can be used as an input data for my Matlab code: each line in that txt file should have the following format:
Node number _ X coordinate - Y coordinate - Z coordinate

Best

Hi Silvia. Where is placed the OpenSeesWiki you name above? I remember a while ago you were very interested in building a WIKI for OpenSees. Are you still working on this project? Is this an advance of what we'll see soon at the OpenSees Board?

Many thanks in advance!

we're working on it, yes, it's almost done.
funny thing, most of the other items on it are done, the manual is dragging on -- as it is the heaviest component!

I'm glad to hear that, Silvia.

Hi Peyman... If you have an unix-based system, then you can use the following script-line at the end of your model file.
exec bash -c { while read line; do if [[ $(echo $line | awk '{print $1}') == node ]]; then echo $line >> nodesFile.out; fi done < modelFile.tcl }

Instructions:
1. Replace the word modelFile.tcl by the path of your model file.
2. Replace the word nodesFile.out by the path of your 'nodes file' (this is the output file).
For example,
- Path of your model file: /Users/hresquivelo/modelFile.tcl.
- Path of your 'nodes file': /Users/hresquivelo/nodesFile.out.

Assumptions:
1. There's not spaces before the definition of command node. I mean,
(incorrect)
.... node 1 0.00 0.00 (suppose that dots are spaces)
(correct)
node 1 0.00 0.00

2. If command node is defined inside a logical-loop statement, then it will not work as expected.


The best way is to make a c++ code.

Thanks Hugo for your guidance!
