Geometry error in newcel

[Jaddyd]

TL;DR

run terminated because 10 particles got lost.
meshtal already exists. meshtam is created instead.
warning. 4 of 4 tallies did not pass all 10 statistical checks.
warning. 4 of 4 tallies were all zeros.

I am facing a problem after running my input file through MCNP 5 it give me these comment
Can any one help me to resolve the error?

I have to make changes to make it work with my old libraries but it runs for me. If the version you attached gives errors can you attach the full output file please?

Kindly receive FYNA

Can you also share with me those changes you've made?

The file you attached has this sdef line,

sdef pos=0.5 0 0 erg=2.45

The file you ran has this sdef line,

sdef pos=0 0 0 erg=2.45

If a source is on a surface the code can make mistakes. 0 0 0 is on surface 8 (px 0). If 0.5 is wrong, only a tiny change is needed to not be 0 so 0.001 should work.

I don't see any other changes and this would explain the fatal error.

Hi Team, I have managed to run my previous input file, after making some changes i run it again it gives me these error

"bad trouble in subroutine unique of xact

cannot create runtpe "

then it stope to proceed. Kindly assist. I have attached my input file

When run MCNP can create a lot of output files, when next run it typically alters a letter and retries. Eventually, 26 letters later it can give up and error. outp, mdata, runtpe, comout and other files depending on what the program is asked for. Move these to a fresh directory or delete if they are not needed, but clear the directory of these files and their 1 letter alts.

Also check you have enough free disk space. A few hundred MB should be easily enough for most problems.

Thank you so much! I see, there is a lot of runtp....... files it needs to be deleted! I appreciate a lot.
