It is also possible to use multiple meshes by passing a list of meshes instead
of a single mesh. This can be useful, for example, when different regions of the
model require different mesh resolutions. The meshes are assumed to be
**non-overlapping**; each element--material combination across all meshes is
treated as an independent activation region, and all meshes are handled in a
single neutron transport solve. For example::
# Fine mesh near the activation target
mesh_fine = openmc.RegularMesh()
mesh_fine.dimension = (10, 10, 10)
...
# Coarse mesh for the surrounding region
mesh_coarse = openmc.RegularMesh()
mesh_coarse.dimension = (5, 5, 5)
...
r2s = openmc.deplete.R2SManager(model, [mesh_fine, mesh_coarse])
