TL;DR
surface 0 not found for cell 101, But I didn't use the surface 0.
Hello,
I am working through the MCNP manual and am experiencing the following error as well as warning when trying to run the sample problem from the manual.
The fatal error I get is
"fatal error. surface 0 not found for cell 1050."
I have upload the output file with the errors in case I have not properly explained what's going on.
