Hello Everyone,

I’m trying to simulate a point source at the origin and I was trying to run this code in the examples and this is the error I get, also to specify that it’s at the origin I should include this line: openmc.stats.Point(xyz=(0.0, 0.0, 0.0) )

Hi @Dalia ;

Just to try to answer about the first error “keyError : 1” it seems to be related to the tally id, you can verifiy by openning your tallies.xml file and look about ids used to identify your tally/tallies!!! or you can try [tallies.id] argument to avoir such like that error.
