MCNP6 is not printing an MCTAL file

AI Thread Summary
MCNP6 is experiencing an issue where an MCTAL file is not generated after running a simulation, despite the creation of an output file. This problem began after encountering a "forrtl: severe <157> : program exception -access violation" error. Attempts to resolve the issue by deleting existing MCTAL files have not been successful, as the problem persists even with no other MCTAL files present. The user believes the missing MCTAL file is related to the initial error encountered. Further investigation into the related thread is suggested for additional context.

I am having an issue with MCNP6. When I run a simulation an output file is created, but not a mctal file. This behavior started after getting the following error

forrtl: severe <157> : program exception -access violation

I restarted and didn't get the error, but now not the mctal file and I think it maybe related. Any ideas?

perhaps too much mctal file created. Try to del all mctal files (mctal, mctab, …)
 
It happens even when there are no other mctal files. I think it has something to do with that error.

Is this thread another description of the problem you had in your other thread?

Yes this was the initial thread when the issue had only happened a few times.
 
Then I will close this thread. Please take a look at the other thread to see if I have answered your question.
 
Hello, I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere...
