AI Thread Summary
The discussion revolves around using MCNPX to apply a mesh tally for calculating and visualizing photon dose distribution. The user seeks guidance on correctly inserting the mesh tally block into their input file for compatibility with the MCNPX Visual Editor. They also need assistance on how to run the mesh tally using the Visual Editor and visualize the results afterward. The user has prior experience with standard tallies but is new to mesh tallies. Help, tips, and examples are requested to facilitate this process.

TL;DR Summary
I'm using MCNPX Visual Editor X_2SS and trying to add a mesh tally (RMESH1:p dose) for photon dose distribution.
I get an error when I add the mesh tally block. I need help on:

- How to properly insert the mesh tally in my input file.
- How to run it using the Visual Editor.
- How to extract and plot the dose results after the simulation
Hi everyone,
I'm currently working with MCNPX and I'm trying to apply a mesh tally to calculate and visualize the photon dose distribution in my geometry.
I have experience using standard tallies like F4 and F5, but this is my first time working with mesh tallies. From the documentation, I understand that MCNPX allows the following syntax for dose mesh tallies:
/////////////
TMESH
RMESH1:p dose
CORA1 0 10i 400.0
CORB1 0 10i 400.0
CORC1 0 5i 150.0
ENDMD
/////////////
I’m using MCNPX Visual Editor.

What I Need Help With:​

  1. How can I correctly insert the mesh tally block into my input file so that MCNPX Visual Editor accepts it?
  2. How do I properly run this mesh tally using the Visual Editor?
  3. After running the mesh tally, how can I visualize the results?
Any help, tips, or examples would be greatly appreciated.

Thank you in Advance.

Hello, I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere...
