I am getting an error code 5 with no description of error what does it mean?
Look into .log, .err and 001.out files (possibly left in the fluka_# temporary directory).
There isn’t any temp directory created .
The run stops as soon as i start it
In fact, the run did not even start since the .flair file was embedding an erroneous .inp path. Loading directly the .inp file has solved the problem.
