Mesh Tally in MCNPX for Dose Calculation / How to Add & Visualize?

[Ayb_mcnp]

TL;DR

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.
