MCNP version 6.2 erroring?

10 June 2024 1 2K Report

I am getting this error in an example problem I found that worked perfectly fine yesterday "bad trouble in subroutine unique of mcnp". I use this command "mcnp6 inp=exampleYay.txt ip" which worked yesterday but now no longer works. What happened?

Dimitrios Kontogeorgakos

Hi Sabrina,

I am not sure if this input in this state was running the previous day and now it does not (unless there were changes). For the input you provided the problem is the format of material 1 (m1); please remember that a continuation line must begin with five blanks otherwise MCNP assumes lines "2.5161e-3" and "92235.66c 1.1760e-3 92238.66c 8.2051e-5" do not belong to any card. Once you fix this formatting error this input runs normally.

PS: When asking about code error it always useful to also include either the output or the fatal error messages.

Good luck,

dimitris
