Dear Ilaria,
Thanks for your answers. however, flair doesn't find the error, but if the geometry has errors, why sometimes the simulations still obtain the needed and correct results (primary#=1E9)shown in figure in the last email? To my understanding, the simulation won't get any simulation results if it has a false geometry.Do you mean the program won't crash as long as the particles don't fall into the false geometry?
Best regards!
Yang.

主题: Re: [fluka-discuss]: Strange problems about the simulations
Dear Yang,
there are actually some errors in your geometry, which are the cause of the crash.
For example you have a superimposition of two regions at x = 0.67, y = 0.67, z = 21.
Please note that this type of errors does not cause an immediate crash, while the program stops immediately if a particle’s position does not belong to any region.
Best regards,
Ilaria

Dear FLUKA users,
Recently I encounter a strange problem. attachments are my simulation files and results. in the beginning, all seems to right, but almost of the calculations fail(see "a4001.log" and it generates a huge size .out and .err file and in the beginningI see the primary particle increases with time,but at the end of 1st cycle the calculation will crash), however, a few of them will get the calculation results("a1001.log"). I check the geometry, and find no problem.If my input file exists problems, no results will be generated.

so what is the problem?
Best regards!
