Task Introduction

In this task you will use OpenMC to calculate the volumes of cells in CSG and DAGMC geometries. Accurate cell volumes are needed for depletion simulations and for normalising tally results to physical quantities (e.g. dose rate per unit volume).

Learning Outcomes

• The volume of a cell or material can be found using the stochastic volume method in OpenMC.

• Stochastic volume calculations have an associated uncertainty that decreases with more samples.

• Volumes of cells in DAGMC geometry can be calculated using pydagmc.
