2 volume_operator(grid, inner_stencil, closure_stencils, parity, direction)
3
4 Creates a volume operator on a `Dim`-dimensional grid acting along the
5 specified coordinate `direction`. The action of the operator is determined by
6 the stencils `inner_stencil` and `closure_stencils`. When `Dim=1`, the
7 corresponding `VolumeOperator` tensor mapping is returned. When `Dim>1`, the
8 returned operator is the appropriate outer product of a one-dimensional
9 operators and `IdentityTensor`s, e.g for `Dim=3` the volume operator in the
10 y-direction is `I⊗op⊗I`.
