First time using FLUKA, the installation went fine and everything seems ok (no errors when installing and everything went according to the installation manual).
I then tried to run the example simulation
rfluka -N0 -M5 example.inp
and I get this error:
9539 Floating point exception: 8 "${EXE}" "${INPF}" > "${LOGF}" 2>&1
Error: "path_to_fluka/fluka4-4.1/bin/fluka" executable returned RC=136
Does anyone know what is the problem here. I didn’t find anything useful on any of the manuals/website.
Thanks for your help and here’s the example.inp just in case. example.inp (3.2 KB)
The PATH that appeared contains /path-to-fluka/fluka4-4.1/bin, the which rfluka command returns /path-to-fluka/fluka4-4.1/bin/rfluka and the ls command returns the following:
AUTHORS LICENSE REFERENCES Version.tag data examples lib
INSTALL README.md RELEASE-NOTES bin doc include src
From the output you provided, your FLUKA installation is directly in the root directory /, which is typically a read-only file system. I suggest you to install fluka in a more standard directory, such as your home (/Users/<your_username>).
For the sake of precision, the PATH environment variable should include also other directories, and not only /path-to-fluka/fluka4-4.1/bin. Do you confirm this is the case?
Moreover, your error message reports the full path of the FLUKA executable as path_to_fluka/fluka4-4.1/bin/fluka, while it should start with a / (according to your info), pointing to some error in the installation.
Cheers, Luigi
P.S. Maybe it was clear but path_to_fluka in the installation instructions does not indicate a specific directory name, rather it is the path where you have installed FLUKA.
But I did install fluka in home, the path is /Users/user/fluka4-4.1. Yes the path that appeared after the echo $PATH command was huge but the last entity was the /path-to-fluka/fluka4-4.1/bin. And finally the path that I sent you and that I got for which fluka does contain a / at the very start.
I don’t know if I’m messing something but the fluka software does run showing the directory, the data, exec and input. When it starts with the first cycle, it shows a floating point exception and that the error is that the excutable returned RC=136.
I didn’t work, I removed everything related to Homebrew from my computer and tried with another Mac with the same setup and the problem is always is the same.
When I run the rfluka -M1 example.inp, I get the following error:
======================== Running FLUKA for cycle # 1 ========================
line 376: 7731 Illegal instruction: 4 "${EXE}" "${INPF}" > "${LOGF}" 2>&1
Error: "/pathtofluka/bin/fluka" executable returned RC=132
