MCNP6 Error: "Geometry error: no cell found"

Click For Summary
The user is experiencing a "Geometry error: no cell found" issue in MCNP6. The solution involves adjusting the bounding sphere to ensure that no objects extend beyond it, as anything outside is considered void. By using the command "mcnp ip inp=filename" and checking specific coordinates, it was discovered that some objects were protruding. Increasing the size of the bounding sphere resolved the issue. The user confirmed that the problem has been solved.

Hello @ameermukhtar,

Welcome to PhysicsForums. Your bounding sphere defines the experiment area, and anything outside it is part of the void. That works so long as no objects poke through. If you run "mcnp ip inp=filename", the default view seems fine. But click on the input box and type "pz 149", to check close to corners of 9 and 10, you can see the corners of 9 (rpp) sticking through it. Just try making the sphere bigger and see if that fixes the problem.
 
can you correct it brother

thank you dear the problem has been solved
 

Thread 'What type of energy is actually stored inside an atom?'

What type of energy is actually stored inside an atom? When an atom is split—such as in a nuclear explosion—it releases enormous energy, much of it in the form of gamma-ray electromagnetic radiation. Given this, is it correct to say that the energy stored in the atom is fundamentally electromagnetic (EM) energy? If not, how should we properly understand the nature of the energy that binds the nucleus and is released during fission?
