AMy personal bias is not to use rpp or rcc. I prefer to use simple planes and cylinders. That's mostly because of what I have wanted to...

Like.
You can probably get a library card at your local university for very little money, maybe free. A medium-to-big uni is likely to have... -

Some journals will. have "open access" articles or issues. Most scientific journals in nuclear science and engineering require purchase...

AAlex A reacted to DEvens's post in the thread Normalization of MCNP F4:P photon flux tally to experimental counts with Like.
Normalization of detectors is a thing. What you need is some way of knowing the number of particles per second in your real system...

AAlex A mentions there being no cell 1504. In the OP there is no surface 1504 either, it's a line number as printed out by MCNP...

AAlex A replied to the thread MCNP IMP:n=0 when IMP:p,e=1.Welcome to Physics Forums @Adina C, I'm a bit confused by the question and a bit confused by the input file. The number of histories...

AAlex A replied to the thread Particles lost in MCNP running.All space in the problem must belong to a cell, and no point in space may belong to more than one cell. That is a complicated input...

AAlex A replied to the thread Normalization of MCNP F4:P photon flux tally to experimental counts.Welcome to PF @Marinaromany, It might be possible to do that with an F4 and a cross section multiplier but F8:p,e is a better way on the...

AAlex A replied to the thread Particles lost in MCNP running.Cell 1300 is the big cell containing the experiment and air, outside that is the void cell. That cell definition is failing and anything...

AAlex A replied to the thread MCNP vs Serpent pin-cell burnup discrepancy in keff evolution.I usually avoid commenting on something so far away from what I know, that said, I think I've spotted something. The main difference is...

AAlex A reacted to DEvens's post in the thread Creating the geometry using MNCPX VisEd with
Informative.
Re: Versions of VisEd. The executable that shipped with the last MCNP 5, and the one with up to MCNP 6.1, and the one that you get from... -
AAlex A replied to the thread Creating the geometry using MNCPX VisEd.I have read the version of VisEd supplied with 6.1 is a plot only version, not the full version. I think I read it's a separate package...

AAlex A reacted to DEvens's post in the thread Creating the geometry using MNCPX VisEd with Informative.
My experience has been that VisEd is only useful to view your MCNP inputs. Trying to edit within VisEd is not worth it. For example, I...
