Dear fluka experts and users,

 

I am running fluka code and the program dies for some particular events. I
have 5 runs and each run has 2000 events. Now I have the 4th .err file in
the fluka_XXXX temporary folder contains the following information:

It is dead after the 61st event. And the ran* file contains these:

The program just dies and seems no error information printed. To be more
efficient, I want to debug only with the problematic event (without running
the previous events). According to the manuals, both of the hexadecimal
numbers in these two files are called seeds. So, my question is that how can
I reproduce the events where the program dies using these "seeds"?

 

 

Thanks in advance,

Guang
