I am currently trying to print some source distributions using the det 'df' option. For the most part it seems to be working, but sometimes when running I am getting warnings printed out that say:

This sounds to me like it is related to the neutron weights, but I am running in analog criticality mode, so I would think all the weights are 1.0. I am running with a few different detectors to print out multiple source distributions:Warning message from function WriteSourceFile:

P larger than 1 (1.356349E+00)

I checked that the warnings are still printed when the fraction parameter at the end of the detector definitions are increased from 0.5 to 1.0, and they are.det batch1 n du 0101 du 0201 du 0301 du 0401 du 0501 du 0601 du 0701 du 0801 du 0901 df sourcefile01 0.5

det batch2 n du 0102 du 0202 du 0302 du 0402 du 0502 du 0602 du 0702 du 0802 du 0902 df sourcefile02 0.5

det batch3 n du 0103 du 0203 du 0303 du 0403 du 0503 du 0603 du 0703 du 0803 du 0903 df sourcefile03 0.5

det batch4 n du 0104 du 0204 du 0304 du 0404 du 0504 du 0604 du 0704 du 0804 du 0904 df sourcefile04 0.5

det batch5 n du 0105 du 0205 du 0305 du 0405 du 0505 du 0605 du 0705 du 0805 du 0905 df sourcefile05 0.5

The stranger part about this is I don't always get the printed warnings. I can't seem to figure out a pattern, but sometimes I do not see the warnings printed in my output.

Any thoughts on what this means?

Thanks,

Chris
