TCL script to load points and forces

Before talking about your code, my question: how do you do with your loaded nodes? How to link to your mesh? your structure?

The loaded nodes will be linked to the mesh with RBE2 or RBE3 elements (depending on the type of load). These will, for now, be implemented manually afterwards.

Use $data instead of data

Use [ ] instead of { }

I think a simpler code can do , don't need structmatrix package, it just messes up your codes

set fpt [open 'coordinates-forces.csv']

set buf [read -nonewline $fpt]

close $fpt

foreach line [split $buf \n] {

   lassign [split $line ,] x y z fx fy fz f

   CreateNode

    CreateForce

}

Okay, so trying the simpler code you provided above, I still get an error.

foreach line [split $buf \n] {
lassign [split $line] x y z fx fy fz f
*createnode $x $y $z
*createmark nodes 1 1
*loadcreateonentity_curve nodes 1 1 1 $fx $fy $fz 0 0 $f 0 0 0 0 0
}

The reason I put [split $line] is because it is actually separated with a semicolon, so a comma wouldn't work.

The error I get is the following: extra characters after close-quote.

I would assume that there might be a problem with the '{' after the foreach command, but I'm not sure.

Any advice?

Take a screenshot about the error please

You can find the error attached.

<?xml version="1.0" encoding="UTF-8"?>

Did you copy code from webbrowser then paste to text editor?

Yeah at first I did. Now, I typed it in myself and it actually gives me another error.

Note that now, I created an extra variable $n to show on which node the force needs to be applied. I checked it in the command file and this should actually work. But, I don't really understand the error showing up now.

<?xml version="1.0" encoding="UTF-8"?>

Use *createmark nodes 1 -1

What the script does now is creating a node at 0 0 0 and a force on that node with components 0 0 0. My test csv file doesn't contain this node, nor a zero force.

I'm not sure what's wrong here?

to debug, try running with a short csv file , maybe 5 lines

I have debugged it! There were some minor errors like \n instead of '\n' and the semicolon separator {;} in the split command. For those of you wondering what the final code looks like, you can find it beneath.

Note: I've added a line to create a loadcollector for each created force.

Thanks for the help tinh!

\n instead of '\n'

I don't think so. Actually \n and '\n' are the same. Anyway, gòod job
