Re: Revised calculation of time constants (version 2.1.13)

I'm running Serpent 2.1.21 and I can't find FWD_IMP_GEN_TIME or ANA_REPROD_TIME (like is written in Manual) .
Where I can find the neutron generation time in the output file?
You changed the name of this variable?

Re: Time dependence in external source

I'm interested on studying the begining of operation of subcritical systems. I was writing the source file in a wrong way. That was not what I wanted. Now I guess I understand. for the external source to operate for 100 seconds my source file randomily peak a time between 0 and 100 second (the last ...

Re: Time dependence in external source

I think I don’t exactly understand how to write a source file or there is something wrong in my Serpent input. I need to measurement first 100 seconds of nuclear subcritical operation for my phd thesis. When I use time binning counter, I only saw neutrons in first output or second one raw (my tme ca...

Time dependence in external source

I saw in a post something I believe to be about time dependence in "Dynamic simulation mode". then I'm trying to use this: set nps 20000 100 intervalos tme intervalos 2 10000 0 0.01 when I use the code above, Detector time binning show me external neutrons behavior like only one pulse in the very be...

Re: Detector time binning

I' m using external neutron source. As cited in other post, when I use "time binning" the simulation is limited only millisecond. There are other way to obtain this in other time scale For example 50 seconds. If not, still under development it? Follows part off my code. set nps 20000 100 intervalos ...
