Install Code_Saturne 2.0-rc1 with Salome 5.1.3 prerequisites

Alexandre_Douce · March 3, 2010, 11:02pm

For the build of Code_Saturne with SALOME it is better to use prerequisites of the installation of SALOME.

The following how-to is based of the use of the install_saturne.py script. I suppose that an installation of Salome 5.1.3 is available.

in the Salome 5.1.3 installation create the following symbolic link ( adapt the paths depending on your installation ):

ln -s /home/salome/Salome_5.1.3/PyQt-4.5.4/bin/pyuic4 /home/salome/Salome_5.1.3/Python-2.4.4/bin/.
ln -s /home/salome/Salome_5.1.3/PyQt-4.5.4/bin/pyrcc4 /home/salome/Salome_5.1.3/Python-2.4.4/bin/.
ln -s /home/salome/Salome_5.1.3/PyQt-4.5.4/bin/pylupdate4 /home/salome/Salome_5.1.3/Python-2.4.4/bin/.

source the environment variables of SALOME:

source /home/salome/Salome_5.1.3/env_product.sh

create the directory in which you want to install Code_Saturne:

mkdir -p /home/saturne/Code_Saturne/2.0-rc1

adapt the setup file of the Code_Saturne installer and particularly the following variables:

prefix /home/saturne/Code_Saturne/2.0-rc1
python /home/salome/Salome_5.1.3/Python-2.4.4/bin
cgns None yes yes
hdf5 /home/salome/Salome_5.1.3/hdf5-1.6.9 yes no
med /home/salome/Salome_5.1.3/med-2.3.6 yes no
metis None yes yes
mpi None yes yes
libxml2 /home/salome/Salome_5.1.3/libxml2-2.6.27 yes no
swig None yes yes

note that a new swig will be downloaded and installed, because the swig embedded with SALOME is too old for the mei library.

finally launch the installer:

./install_saturne.py

on the terminal you will have this output:

    Installation of Code_Saturne
The process will take several minutes.
You can have a look at the log file meanwhile.

Check the setup file and some utilities presence.
Installation of CGNS
Installation of MPI
Installation of Swig
Installation of BFT
Installation of FVM
Installation of MEI
Installation of ECS
Installation of NCS

Before using Code_Saturne, please update your path with:

cspath=/home/saturne/Code_Saturne/2.0-rc1/cs-2.0-beta2/bin

export PATH=$cspath:$PATH

The documentation should then be available through the commands:

code_saturne info -g refcard

code_saturne info -g user

Thank you for choosing Code_Saturne!

create a launcher for SALOME with CFDSTUDY and Code_Saturne:

#!/bin/sh
source /home/salome/Salome_5.1.3/env_products.sh
CS_HOME=/home/saturne/Code_Saturne/2.0-rc1/cs-2.0-beta2
export PYTHONPATH=$CS_HOME/lib/python2.4/site-packages:$PYTHONPATH
export PYTHONPATH=$CS_HOME/lib/python2.4/site-packages/mei:$PYTHONPATH
$INST_ROOT/KERNEL_5.1.3/bin/salome/runSalome --modules=GEOM,SMESH,CFDSTUDY,VISU,MED --killall

It is interesting to see this. May I say by this method I can integrate Code_Saturne into the SALOME platform? I am sorry but I used them seperatedly.

I can compare with my post “Compile Code_Saturne with SALOME binary libraries” on http://code-saturne.blogspot.com

Hi Wayne, there is no trouble to use Salome and Code_Saturne seperatedly

With the method described above, Code_Saturne is build with the prerequisites of Salome. Fisrt, this allows a compatibility between the two softwares mainly regarding the med format for meshes, and secondly, it allows the integration of the GUI of Code_Saturne in the desktop of Salome if the plugin CFDSTUDY is installed as an additional module of Salome (see here).

It seems that there are some issues with the installation of Metis in the prerequisites of Salome and the installer
As said here it is possible to not use Metis, and to use the internal partitioner of Code_Saturne.

Hi Alexandre,

I 'd like to install code_saturne with Salome, but there is something wrong with my PyQt libraries. I followed your description above but I get always the same error massage:

What can I do??

Hello,

are you sure the SALOME environment correctly ? If you did, do you have another installation of qt4 or pyqt4 which might be mixed with the SALOME environment ? In any case, if things do not work right away with a minor correction, I would suggest upgrading to SALOME 5.1.4, in case it includes bug corrections which may help.

Best regards,

Yvan

Hello Yvan,

is it compulsory to use the same python libraries when installing code saturne as a plugin within salome ? I could install CFDSTUDY but when running Salome the message ‘CFD Code environment not found!’ appears. Maybe I have to set some additional variables in a shell script fpr activating CFDSTUDY? I already set the CFDSTUDY_ROOT_DIR in envSalome-V5.1.3.sh .

Best regards

Thomas

Hello,

the message ‘CFD Code environment not found’ means that the solver is not found. You have to complete your PYTHONPATH variable, you could try these commands :

source /home/salome/Salome_5.1.3/env_products.sh
CS_HOME=/home/saturne/Code_Saturne/2.0-rc1/cs-2.0-beta2
export PYTHONPATH=$CS_HOME/lib/python2.4/site-packages:$PYTHONPATH
export PYTHONPATH=$CS_HOME/lib/python2.4/site-packages/mei:$PYTHONPATH
$INST_ROOT/KERNEL_5.1.3/bin/salome/runSalome --modules=GEOM,SMESH,CFDSTUDY,VISU,MED --killall

As mentioned here http://code-saturne.org/forum/viewtopic.php?f=8&t=1022 you can put these commands in a launcher (i.e. an executable file).

Let us know if it works

Thomas_Aumeier · December 20, 2010, 4:05pm

Hello,

Salome with CFDSTUDY is working now. The problem was simple (as usual ) . I already used a laucher but with

export PYTHONPATH=$CS_HOME/lib/python2.6/site-packages:$PYTHONPATH
export PYTHONPATH=$CS_HOME/lib/python2.6/site-packages/mei:$PYTHONPATH

instead of

export PYTHONPATH=$CS_HOME/lib64/python2.6/site-packages:$PYTHONPATH
export PYTHONPATH=$CS_HOME/lib64/python2.6/site-packages/mei:$PYTHONPATH

Sorry for the confusion!

Best Regards

Thomas
