hello,

I am new to linux and OpenFOAM. I'm trying to run the motorBike tutorial. When I try to run it with sudo ./Allrun, I get the following error :

./Allrun: 3: .: Can't open /bin/tools/RunFunctions

I understand this can be a problem with the variable $WM_PROJECT_DIR. Here's what I get with echo $WM_PROJECT_DIR :

/opt/openfoam211

So, anyone knows why I get this error?

[alexeym]

Hi,

did you do

$ source /opt/openfoam211/etc/bash

before running the script? If yes, show, please, your environment with a command

$ export | grep -E '(WM_|FOAM_)'

to see if it really set up.

Thanks for the help. Here's what I get with this command :

Well, environment variables are correct. Don't know, maybe they weren't set up in the terminal where you've executed Allrun script.

[jul059]

I forgot to say,

source /opt/openfoam211/etc/bash

gives the following error :

bash: /opt/openfoam211/etc/bash: No such file or directory

[alexeym]

Oh, sorry, maybe it's autocorrect but the right command is

source /opt/openfoam211/etc/bashrc

[jul059]

I ran

source /opt/openfoam211/etc/bashrc

and the result is the same.

When I run

sudo ./Allrun

I get the following :

./Allrun: 3: .: Can't open /bin/tools/RunFunctions

But if I run it without sudo, I get the following :

cp: cannot create regular file `constant/triSurface/motorBike.obj.gz': Permission denied
blockMesh already run on /home/julien/OpenFOAM/julien-2.1.1/run/incompressible/simpleFoam/motorBike: remove log file to re-run
snappyHexMesh already run on /home/julien/OpenFOAM/julien-2.1.1/run/incompressible/simpleFoam/motorBike: remove log file to re-run
potentialFoam already run on /home/julien/OpenFOAM/julien-2.1.1/run/incompressible/simpleFoam/motorBike: remove log file to re-run
simpleFoam already run on /home/julien/OpenFOAM/julien-2.1.1/run/incompressible/simpleFoam/motorBike: remove log file to re-run

How do we explain that the script seems to execute further without sudo?

As I said, I am new to OpenFOAM AND Linux...

[alexeym]

Well, you've got 2 problems here

1. If you run Allrun with sudo, script has different set of environment variables

2. You don't have write permission in /opt/openfoam211/tutorials

So you can do something like this:

$ source /opt/openfoam211/etc/bashrc
$ cd $FOAM_RUN
$ cp -r $FOAM_TUTORIALS .
$ cd tutorials
$ ./Allrun

These commands will copy tutorials folder for your home folder where you have write permission, and after you'll be able to run them.

I was finally able to run the script. The source of my problem was rather obscure : a faulty hard drive. I replaced it, reinstalled CAELinux and everything is fine.

Thank you for your help!
