To really see that the source is isotropic, i.e. the particle flow is equally distributed throughout the source volume. Everything is already transparent. Thanks for your answer, I'll try it.

Hello everyone! I need to make sure that my source is isotropic. How can I check that? I have point source pos -11 0 0 erg=d1 with Maxwellian spectrum of energy and some surfaces through which neutron flux passes.

This is the surface of the cube, that is, one side of it. I tried to make a cell source of it, but i don't understant how to do it correctly. For the cell source I need to write from which cell neutron flux starts and add some distributions of the cell, if I correctly understand. But I also have...

Yes, it has to be a surface..

Hello everyone! I have to use isotropic distribution for my mcnp program. But I didn't find how can I create that one.

Thanks a lot! Probably I misinterpreted the output file...

Hello everyone! I have some troubles with my MCNP programm: I have a source, a moderator and a tally. The source is surface, the moderator is water (but I need to calculate for vacuum as well). Only neutrons are used in this task. The neutron flux is unidirectional. I take 1e6 the number of...
