No input data found for 'snre_gcr_source_v2_0.bnn'

Hello,

I’m modelling a proton source in a rocket to calculate an induced neutron source. I have managed to run a file successfully. However, when trying to process the data in Flair, I get the error ''WARNING: No input data found for ‘snre_gcr_source_v2_0.bnn’". According to Flair there are no geometry errors. There are some warnings due to intersecting planes but I’m not sure how to get around these without changing the geometry. The .err files show the following:

but I’m not sure how to interpret this.

Thanks in advance,

Dear Emma,

on the Run tab - Data section, you can edit the Name/Unit of the detector to 50.

The error file is cut short because you set the sequential_logical_flag to .true. in the source routine. This will stop the simulation when all lines in the phase-space file are simulated once.

Cheers,
David
