using transformPoints in a bash script

Hi everyone.

I would like to ask a "probably" very easy question. I am a little bit newbie at linux bash scripting.

I have a center of mass point "p", which comes from another calculation. How can I use it in tansformPoints command? I tried these different ways below but it does not work...

p="(0 0 0)"
transformPoints -translate '($p)'

p=\'$\ 0\ 0\ 0\ $\'
transformPoints -translate $p

trans='transformPoints'\ '-translate'\ \'$0\ 0\ 0$\'
$trans

I do not know should I post it at linux forums or openfoam forums.

Have you sourced OpenFOAM bashrc before executing the bash script or inside the bash script?

Don't know the error type you get, yet the bash script should be informed regarding the OpenFOAM command 'transformPoints'.

Hi. Thank you for your response.

Yes I did. The other commands at my script are working. Like blockMesh or checkMesh. The error I got is:

"--> FOAM FATAL ERROR:
Wrong number of arguments, expected 0 found 2

FOAM exiting"

Have a go, if possible:

Code:

#!/bin/sh                                                                                                                                                                                     

cd ${0%/*} || exit 1                        # Run from this directory           

                                                                                

vector="(0 0 20)"                                                               

                                                                                

transformPoints -translate "$vector"

Thank you very much sir. It worked.

I tried lots of configurations but seems like I missed this one.

Thanks again, have a nice day.
