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 everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information(power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.) for Material 2 is zero, while Material 1...
Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
