run_hisafe() produces no error, but the output folder is empty

When you encounter this problem, run_hisafe() reports that all simulations were run, but each simulation took only a fraction of a second, and the output folder remains empty. This is annoying because there is no way of knowing what is wrong. Actually the problem is not with hisafer, but with capsis installation (i.e. with java), but I thought it is usefull to talk about it here, in order to help future users who might get stuck with this issue. Here are the most frequent problems (and their solutions):

• java is not the right version (currently version 1.8 should be used), this can also lead to the following error being printed "Probleme loading simulation file java.lang.UnsatisfiedLinkError: Unable to load library 'SticsV8': Native library (darwin/libSticsV8.dylib) not found in resource path (here a long list of files is given)". To check which version of java is in use, type in Terminal or command prompt: java -version if it is anything different from 1.8, download and install 1.8 (e.g. here:http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html). Be careful about the 32-64 architecture (see next point). If you need to keep java 1.9 for other applications, you don't need to down grade (at least on Mac) : you can run more than one version of Java on MacOS, by setting the version of your terminal with this command in MacOS Terminal: export JAVA_HOME=$(/usr/libexec/java_home -v 1.8) (or 1.9 to return to version 1.9)
• java is not in the right architecture : on computers having both windows 32bit and windows 64bit (e.g. windows 7 or windows 10), the web browser usually remains in 32bit, so the java installer installs java 32 bit by default. You need to manually install java 1.8 64 bit. It is available for download here: https://java.com/en/download/manual.jsp. Choose “Windows Offline (64 bit)”. The installation file may need to be run as administrator. When opened, before pressing the install button on the first pop-up window, chech the change directory checkbox in the bottom-left corner. In the next screen, check that the files will indeed be installed in Program Files, not Program Files(x86). You then need to uninstall capsis (go to the Uninstaller folder within capsis folder and double click on uninstaller.jar) and re-install hi-safe from the downloaded installation file (e.g. Hi-sAFe_4.0.0.jar)

In order to check if it works (or to get error messages if it fails), you have to launch capsis form the Terminal or command prompt: on Mac cd /Applications/capsis sh capsis.sh the first line should read: -> OS/JVM/memory: mac/64/1024m on Windows: cd C:\Program Files\Capsis capsis the first line should read: -> OS/JVM/memory: windows/64/1024m on Linux it should read -> OS/JVM/memory: linux/64/4000m don't worry for now about the last number: it's the memory allocated (you should increase it (see the installation guide, step 3: https://www1.montpellier.inra.fr/wp-inra/hi-safe/en/guide-dinstallation/) if your simulations need a lot of memory (e.g. large scene or very deep soil).

Sorry for the long message. I'll add other issues leading to the same symptoms as I encounter them when running Hi-sAFe on different machines....

another problem that has been encountered by some users: nothing happens when trying to launch capsis from the command prompt. Solution: If capsis has been installed on another disk (e.g. D: or E:), you need to use the option /d to change the directory to it: cd /d E:\Mes_documents\capsis
