Cuboid¶
Defines a cuboid domain in space and a predicate whether a given position is inside or outside of the domain.

class
halmd.mdsim.geometries.
cuboid
(args)¶ Construct cuboid geometry instance.
Parameters: - args (table) – keyword arguments
- args.lowest_corner (table) – coordinates of the lower left corner
- args.length (table) – cuboid edge lengths
- args.precision (string) –
floating point precision (optional)
The
lowest_corner
specifies the coordinates of the lower left corner of the cuboid, i.e., the minimal coordinates.The supported values for
precision
aresingle
anddouble
. Ifprecision
is not specified, the precision is selected according to the compute device:single
for GPU computing anddouble
otherwise.
Note
This module does not perform a validation of the meaningfulness of the domain, i.e. it does not test whether the geometry is placed outside the simulation domain.

lowest_corner
¶ Coordinates of lower left corner.
-
length
¶ Edge lengths of cuboid.
