copy cache file to each processor
 

Hi

I have to copy a data file, that each processor would require, into the respective constant directories of the processors.

Is there a simpler way to do this, than to manually do "cp constant/cachefile processor(n)/constant" for each of the N processors whenever I try to run a case.

Maybe a script that I can write just once, and use whenever a case is run?

Any help is appreciated.

Thanks!

Hi newOFuser,

This command line will copy the file "file_name" as you asked:
The way I see it, you have 3 options:

1. You can create an alias command for this line. For example, add this line to "~/.bashrc":
   Code:

   ---

   alias copy_constant_file='for a in processor*; do cp constant/file_name $a/constant/file_name; done'

   ---

2. You can create a script and place it somewhere visible, namely in OpenFOAM's "bin" folder or on your home folder "~/bin".
3. Or the best option, which gives you a better implied documentation method: use the same types of scripts as Allrun and Allclean that OpenFOAM's tutorials use! See for example the ones in "incompressible/simpleFoam/motorBike/".

Best regards,
Bruno

Thanks!

Option 3 works like a charm! ;)
