MCNP, you are a thing.

If I run your case on MCNP6.1 I get Windows telling me MCNP has stopped working.

If I use a smaller NPS number, say 400000 instead of 1000000, then it runs to completion.
If I take out the DE4-DF4 data, it runs to completion.

I'm thinking a bug in version 6.1, some kind of memory overflow that only shows up when you reach some kind of limit in FMESH.

Is it an option to step up to version 6.2?

I submitted a request for 6.2 last night, but I need to get my data in the next week so that I can write and be finished by January. The confusing thing is that it was running up until Friday.
 
Hi

Met with someone form our ITS department and he thinks it's one of three issues. Memory allocation, read/write or access/permission.
