Class ForceRegion

python/simulation.py:571–595

A region (volume, plane, line, or point) in which to compute the integral of the stress tensor of the Fourier-transformed fields. Its properties are: + **`center` [ `Vector3` ]** — The center of the force region (no default). + **`size` [ `Vector3` ]** — The size of the force regi

    A region (volume, plane, line, or point) in which to compute the integral of the
    stress tensor of the Fourier-transformed fields. Its properties are:

    + **`center` [ `Vector3` ]** — The center of the force region (no default).

    + **`size` [ `Vector3` ]** — The size of the force region along each of the coordinate
      axes. Default is `(0,0,0)` (a single point).

    + **`direction` [ `direction constant` ]** — The direction of the force that you wish
      to compute (e.g. `X`, `Y`, etcetera). Unlike `FluxRegion`, you must specify this
      explicitly, because there is not generally any relationship between the direction of
      the force and the orientation of the force region.

    + **`weight` [ `complex` ]** — A weight factor to multiply the force by when it is
      computed. Default is 1.0.

    + **`volume` [ `Volume` ]** — A `meep.Volume` can be used to specify the force region
      instead of a `center` and a `size`.

    In most circumstances, you should define a set of `ForceRegion`s whose union is a
    closed surface lying in vacuum and enclosing the object that is experiencing the
    force.
