Thank you Thomas for those files !

# How to do it


## Creating many folders

To create the folders type in the Terminal :

~~~literatec
amansur@cezanne:~/right_folder$ sh createfolders.sh
~~~

*Note : you have to be in the folder where the file 'createfolders.sh' is, in the Terminal directory adress (**~/right_folder**).*

### createfolders.sh

~~~literatec
#! /bin/bash
COUNTER=5
Updater=1
echo Creating Folders
for i in $( seq $COUNTER )
do
mkdir $i
done
echo Created $COUNTER Folders
~      
~~~

## Succession of simulations

Put the files you want to compute, with the [Makefile](http://basilisk.fr/src/Makefile) in the different folders you just created and put the right value into those files (*for example: change the value of Ca, Re, the level, the size of the box, ...*).

Then launch the 'succession_simulation.sh' file by this command : 

~~~literatec
amansur@cezanne:~/right_folder$ sh succession_simulation.sh
~~~

*Note : you have to be in the folder where the file 'createfolders.sh' is, in the Terminal directory adress (**~/right_folder**).*

### succession_simulation.sh

~~~literatec
#! /bin/bash
clear
StartTime=$(date +%s)
gnome-system-monitor &
echo $StartTime
echo 'Starting Sigma Lineari'
COUNTER=5 #Number of folders
for i in $( seq $COUNTER )
do
dirname="/poisson/temporaires/amansur/Stage_M2/" #Path to your folder
dirname=$dirname$i
cd $dirname
echo $dirname
inputfile="/input"
file=$dirname$inputfile
echo $file
ls
make sigma_lineaire.tst
wait
cd ..
sleep 5
done
StopTime=$(date +%s)
#echo $StopTime
TotalTime=$(($StopTime - $StartTime))
echo "$(($TotalTime/3600)) h $(($TotalTime/60)) m $(($TotalTime%60)) s elapsed."
StartTime=$(date -d @$StartTime)
StopTime=$(date -d @$StopTime)
~~~

if the loop doesn't work, use that code :

~~~literatec
#! /bin/bash
clear
StartTime=$(date +%s)
gnome-system-monitor &
echo $StartTime
echo 'Starting Sigma Lineaire'
for i in 1 2 3 4 5
do
dirname="/poisson/temporaires/amansur/Stage_M2/" #Path to your folder
dirname=$dirname$i
cd $dirname
echo $dirname
inputfile="/input"
file=$dirname$inputfile
echo $file
ls
make sigma_lineaire.tst
wait
cd ..
sleep 5
echo $(pwd)
done
StopTime=$(date +%s)
#echo $StopTime
TotalTime=$(($StopTime - $StartTime))
echo "$(($TotalTime/3600)) h $(($TotalTime/60)) m $(($TotalTime%60)) s elapsed."
StartTime=$(date -d @$StartTime)
StopTime=$(date -d @$StopTime)
~~~

# How to check a variable during computation

Since the computation is going to take a while, it would be nice to be able to follow at where the simulation is. To do this, you can open a new terminal (Ctrl+Alt+T), go to the right folder and type in the command line of the terminal : *"tail -f t.dat"*



## In the file

~~~literatec
FILE * fp_t = fopen ("t.dat", "a");
fprintf(fp_t,"%g %d\n",t,i);
fclose(fp_t); 
~~~

## In the terminal

~~~literatec
> tail -f t.dat
~~~
