Producing 1.6 TB files and run stops due to low storage

Running and Runtime Errors
1

Dear experts,
Kindly see the attached files which are .flair, .inp, .err, .log and .out.

The files is running succesfully for 1 or 2 cycles. Then it stops due to low storage space in the computer. I have checked the size of the file after running of 2 cycles is ~ 1.6 TB which is very impractical.
It seems that there is some error in the input files but I am not able to detect that.

Any help will be beneficial for me.

Thanking you in advance.

Dear Arghya,

I can’t reproduce the issue, can you tell me which files grow unlimited?

Cheers,
David

Case 1: When I am running for monoenergetic carbon ions, it is running smoothly.

Case 2: When I am compiling the source.f file, and running the file with less number of histories ~ 1E5, it is running without any error but uncertainty is large. To, reduce the uncertainty, When I am making the histories ~ 1.6E9 (as in the case of attached input files), the error is occurring i.e after 2 cycles, run stops showing low storage space.

Dear Arghya,

there was a bug in the annular sampling in the source_newgen.f routine a few years back. Please update your routine to the latest version.

Cheers,

Thank you very much for your reply. So I need to take the latest source_newgen.f routine (as attached). Am I correct ?
The syntax is: call sample_annular_distribution( 0.0D0, 0.001D0, coordinate_x, coordinate_y )
This is for FLUKA version 4-3.0
Or, how to update the routine?
Any clue will be helpful to me.

Dear Arghya,

you need to take source_newgen.f from the latest FLUKA release, and copy over the changes you made. The syntax of the routine did not change.

Edit: Please, don’t forget to recompile your executable after changing the user routine.

Cheers,
David
