    Error Mcnp
AI Thread Summary
The user is encountering a fatal error in MCNP due to missing cross-section tables, specifically in the xsdir file. They have created a symbolic link to a custom cross-section directory, which mirrors the original xsdir file but with different library names. Despite ensuring that the DATAPATH and PATH variables are correctly set in their configuration files, the error persists even when using the default xsdir file. The issue appears to be related to the MCNP5 version 1.60 setup, and the user is seeking solutions to resolve the error. Further assistance is requested to troubleshoot this problem effectively.

fatal error. *** cross-section tables are missing from xsdir

bad trouble in subroutine ixsdir of imcn
cannot continue with missing cross-section table(s).

is the message I am getting. I have created a link using

ln -s /file/path/to/LANL/MCNP_DATA/mycustomxsectiondirectory xsdir

to direct MCNP to my custom x-section directory when it is looking for xsdir. The custom directory is identical to the xsdir file created during the mcnp install, aside from the names of the libraries. The custom libraries that are listed in the directory are in the same folder with the rest of the libraries from MCNP. My DATAPATH and PATH variables are set to the correct locations in both my .bashrc and .bash_profile files.(DATAPATH is set to the /LANL/MCNP_DATA folder and path is set to the /MCNP5/bin folder) I tried using the default xsdir file to see if it was an issue with my custom directory, and it gave me the same error. I'm not sure why it is giving me this error. It is MCNP5 ver. 1.60. Thanks for any help!

Thread 'MCNP6 BURN Card Issue: Zero Burnup for Material in Fuel Assembly'

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...
