Hi everyone,

I really need help on running multiple OpenFOAM versions. I have been using OpenFOAM-3.0.1 for 1.5 year already but mostly only modifying on modifying and creating solvers nothing fancy and it has been working great. At this point, I need to use blockMatrixTools to solve a set of equations so I downloaded foam-extend-3.1 version following below link.

http://openfoamwiki.net/index.php/In...oam-extend-3.1

I then added below to .bashrc file

cd ~/foam/foam-extend-3.1
source etc/bashrc
 
echo "alias fe31='source \$HOME/foam/foam-extend-3.1/etc/bashrc'" >> $HOME/.bashrc

Then I opened .bashrc file and modified my original version by adding this line

alias of30='source \$HOME/OpenFOAM/OpenFOAM-3.0.1/etc/bashrc'

According to this link

http://openfoamwiki.net/index.php/In...with_the_Shell

In .bashrc file, this below line already exists, I am not sure if it was me who did this when I started working on OpenFOAM 1.5 year ago or it was originally there.

source /opt/openfoam30/etc/bashrc

So I deleted this line in .bashrc file then I went back to check my original version (OpenFOAM-3.0.1)

~/OpenFOAM/OpenFOAM-3.0.1

but after I used source etc/bashrc, it shows follow error

bash: /home/myName/foam/OpenFOAM-3.0.1/bin/foamEtcFile:
 No such file or directory
bash: /home/myName/foam/OpenFOAM-3.0.1/bin/foamCleanPath:
 No such file or directory
bash: /home/myName/foam/OpenFOAM-3.0.1/etc/config/settings.sh:
 No such file or directory

So I am wondering what I did wrong on .bashrc file, right now, it looks something like (cat .bashrc)

alias of30='source \$HOME/OpenFOAM/OpenFOAM-3.0.1/etc/bashrc'
alias fe31='source \$HOME/foam/foam-extend-3.1/etc/bashrc'

I am not sure if there is supposed to be more lines in .bashrc file?

If I type

ls /opt

here is what I get

openfoam30 paraviewopenfoam44

Now if I try to switch between the two using of30 or fe31 that I set earlier in .bashrc file. I get following errors when I choose of30 (OpenFOAM-3.0.1) but no error at all for fe31(extend-3.1):

bash: /home/myName/foam/OpenFOAM-3.0.1/bin/foamEtcFile:
 No such file or directory
bash: /home/myName/foam/OpenFOAM-3.0.1/bin/foamCleanPath:
 No such file or directory
bash: /home/myName/foam/OpenFOAM-3.0.1/etc/config/settings.sh:
 No such file or directory
bash: /home/myName/foam/OpenFOAM-3.0.1/etc/config/aliases.sh:
 No such file or directory

Which is similar to error I get when I did source etc/.bashrc

On of30 if I type

echo $WM_PROJECT_DIR

I get

/home/myName/foam/OpenFOAM-3.0.1

and if I type

echo $WM_PROJECT_USER_DIR

I get

/home/myName/foam/myName-3.0.1

Additionally, when I tried to compile one of my solvers that I built under $HOME/OpenFOAM/myName-3.0.1/applications/solvers, which is where I usually work on modifying my solvers, with wmake, I kept getting no such file or directory on many .H files included in the solver, i.e. #include "fvPatchFields.H" or "fvCFD.H". That led me to think that this installation of extend-3.1 must have messed with current environment as I have not changed anything on my OpenFOAM-3.0.1 at all, only changed .bashrc file.

I have attached file bash files from etc/bashrc from both OpenFOAM-3.0.1 and extend-3.1 as shown in attached files.

I have been trying to find solutions from many sites but have yet to figure out how to fix this problem. Now, I only want my original version (OpenFOAM-3.0.1) to at least work so I can continue to work on something I was working on previously. As for extend-3.1, I also tried to compile some random solver but got the same error as when I tried to compile 3.0.1 version, which is something is missing (no such file or directory).

Please kindly advise what part I did wrong or how to fix this problem? Any advices or suggestions would be highly appreciated.

Thank you.

Greetings Rolanzo,

The problem seems to be that the instructions that you followed were not clear enough on how the "~/.bashrc" file should be modified.

I've updated the instructions on the foam-extend related installation pages at openfoamwiki.net, so that it's clearer that the users are meant to simply run the commands given there, instead of manually editing the ".bashrc" file themselves.

Now, in your "~/.bashrc" file, I ask you to:

1. First, make a copy of that file, so that you don't loose anything vital from it, in case you accidentally erase something critical.
2. Then edit that file "~/.bashrc" in a text editor, then remove all of the lines that refer to OpenFOAM and foam-extend in that file of yours.
3. Next, add the following 3 lines to the end of that file:
   

   alias of30opt='source /opt/openfoam30/etc/bashrc'
   alias of301='source $HOME/OpenFOAM/OpenFOAM-3.0.1/etc/bashrc'
   alias fe31='source $HOME/foam/foam-extend-3.1/etc/bashrc'

   The main problem you had is that the backslash "" did not allow the "HOME" variable to be properly used.
4. Save and close this file in the text editor.

After this, the following steps should get things up and running again:

1. Start a new terminal command line and run the following commands:
   

   echo $WM_PROJECT_DIR
   export | grep FOAM

2. These two commands should not give you any output. If they go give any text referring to paths of OpenFOAM or foam-extend, then you will need to log out and then log back in.
3. If the commands in step #1 didn't give any output, then run the following command:
   

   of30opt

   It should load the OpenFOAM 3.0 installation that you have in "/opt/openfoam30".
4. Next, open another new terminal window or tab and test running the following command:
   

   of301

   which should load your OpenFOAM 3.0.1 installation that you have at "~/OpenFOAM/OpenFOAM-3.0.1" (reminder: it's the same as "$HOME/OpenFOAM/OpenFOAM-3.0.1").
5. Similarly, open a new terminal window or tab and test running the following command:
   

   fe31

   for foam-extend 3.1.
6. Keep in mind that whenever you need to use a specific version of OpenFOAM or foam-extend, you must only use 1 version per terminal window or tab.

Hopefully this solves your problem. If not, please report any error messages you get on each step.


Best regards,
Bruno

Hi wyldckat, Thank you so much for your response! I am now able to run both OpenFOAM-3.0.1(of30) and foam-extend-3.1 (fe31). However, I still have some problem regarding compiling a solver on foam-extend-3.1. I am trying to build a solver based on blockCoupledScalarTransportFoam. I started by copying an original solver and trying to compile using wmake. But here is what I get after wmake:

fatal error: fvCFD.H: No such file or directory
#include "fvCFD.H"

This fvCFD.H is the first file included in the solver blockCoupledScalarTransportFoam. I tried to create more solvers based on other solvers in foam-extend-3.1, i.e. elasticSolidFoam, but still ended up getting the same error, which is no such file or directory. So I am wondering if I need to link some library to this version for the solver to see all these files? I do not have such problem when I create solver on OpenFOAM-3.0.1.

Thank you in advance for your help!

Today when I turned on my computer to start working. I tried again and when I opened a new terminal and typed fe31 to run extend-3.1. I got an error that I did not get yesterday as below, not sure whats going on.

modprobe: ERROR: could not insert 'fglrx': No such device
Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly
modprobe: ERROR: could not insert 'fglrx': No such device
Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly
modprobe: ERROR: could not insert 'fglrx': No such device
Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly

Do you have any idea on how to fix this problem? Do I have to download a new kernel? OpenFOAM-3.0.1 is still working fine, only extend-3.1 that has problem. My Ubuntu version is 14.04. I do not want to try something myself that I am not sure as it could make the problem worse like what happened before.

Thank you.

Quick answers and sorry for the late replies:

If that solver is from foam-extend, then it will never build with OpenFOAM 3.0.1, unless you bring all of the blockCoupling mechanisms from foam-extend to OpenFOAM.
Either way, the error is because the include path for either "finiteVolume" or "OpenFOAM" is missing. For example, from here: https://github.com/OpenFOAM/OpenFOAM...m/Make/options

EXE_INC = \
    -I$(LIB_SRC)/finiteVolume/lnInclude \
    -I$(LIB_SRC)/fvOptions/lnInclude \
    -I$(LIB_SRC)/meshTools/lnInclude \
-I$(LIB_SRC)/sampling/lnInclude

Thank you.

It's possible that the drivers for the AMD graphics card were updated or the kernel was updated, but it was in such a way that the OpenGL library changed files names or something.

It's been a while since you asked, so I don't know if you managed to solve the problem.
