In OpenMC parlance, what is a cell "instance"?

(Select all that apply) When wrapping OpenMC in MOOSE, at a minimum, which auxiliary variables does the user need to create?

(Select all that apply) You are creating an OpenMC wrapping with the following syntax. Which auxiliary variables are automatically created by Cardinal to send data in/out of OpenMC?

True or False: A MOOSE mesh element must be fully contained within a single OpenMC cell.

(Select all that apply) An OpenMC cell can contain multiple MOOSE mesh elements as long as:

When building an OpenMC model, under which conditions will a cell receive unique temperatures?

(Select all that apply) What AuxKernels can you use to visualize how the OpenMC geometry and materials get mapped to the [Mesh]?

Suppose I build an OpenMC geometry as the following. How many levels are in this geometry?

• A rectangular box, which contains universe 4
• Universe 4 is a 3x3 rectangular lattice, where each component in the lattice is filled by universe 5
• Universe 5 is a 4x4 rectangular lattice, where each component in the lattice is filled by universe 6
• Universe 6 is an infinite region of uranium metal

(True or False) Suppose I then set solid_cell_level = 0. My entire OpenMC model will be set to a single temperature because level 0 in the geometry contains all other cells.

Suppose I instead set solid_cell_level = 2. How many unique temperatures will be set in my OpenMC model?
