Discussion Overview

The discussion revolves around an issue with the MCNPX simulation output, specifically concerning the proton energy values being reported as zero in the output file. Participants are examining input and output files to troubleshoot this problem, which involves technical aspects of the MCNPX software and its output formatting.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant reports that the output for f6:p1 is zero while f6:n1 has values, seeking assistance to resolve this.
  • Another participant points out that f6:p refers to photons, suggesting a change to f6:h for protons.
  • A participant confirms they made the suggested change to f6:h but still receives zero values for certain cells.
  • There is a suggestion to check the output file for errors and warnings, emphasizing the importance of reviewing it for troubleshooting.
  • Another participant notes the need to rename the output file to attach it properly, indicating a potential issue with file submission.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the cause of the zero values in the output. Multiple views on how to address the issue are presented, and the discussion remains unresolved.

Contextual Notes

Participants mention the importance of correctly identifying the type of particles in the MCNPX output and the need for proper file attachments for effective troubleshooting. There are indications of potential misunderstandings regarding the output formatting and particle identification.

output file proton energy is zero ???????? in mcnpx
Hello everyone
please look on these input and out put file in the files neutron400. txt and neutron400.out i am facing a problem. in neutron400.out when you will see the output than you will see that f6:n1 2 3 4 5 6 7 8 9 etc.... but in the same time f6:p1 2 3 4 5 6 7 8 9 is zero and i want this output for f6:p1 2 3 4 5 6 7 8 9 . can anyone please help me

I'm not seeing the output file attached yet...
 
f6:p is photon, not proton. Change to h.
 
i also changed but the result is same i.e i can not get the values for f6:p1 2 3 4 5 6 7 8 9

The file you are posting is the input file. It's helpful to read the output file because it gives you errors and warnings that are sometimes helpful.

All :p cards need to be :h cards ( or deleted). So f6:p needs to be f6:h, imp:p needs to be imp:h. First make the change. If the answer is still not right post the output file.
 
please find attach here my output file with f6:h 1 2 3 4 5 6 7 8 9 but cell 4 5 6 7 is value of h is zero
 
You will need to rename the .out file to .txt to attach it. Try giving it a different name like neutron400out.txt
