itasca.pebblearray

Array interface for Itasca pebbles.

Functions

itasca.pebblearray.extra(slot: int) → array float{pebble} or float{pebble}.

Get the pebble extra data in the given slot as an array. Extra variables accessed by array must be of type float or vec.

itasca.pebblearray.fill_pos(data: array float{pebble, 2}) → None.

Fill an existing array with the pebble location. The array must be the correct shape.

itasca.pebblearray.fill_radius(data: array float{ball}) → None.

Fill an existing array with the pebble radii. The array must be the correct shape.

itasca.pebblearray.fill_vel(data: array float{pebble, 2}) → None.

Fill an existing array with the pebble velocity. The array must be the correct shape.

itasca.pebblearray.ids() → array int{pebble}.

Get the pebble ids as an array.

itasca.pebblearray.in_group(group_name: str, slot=1) → array bool{pebble}.

Return pebble group membership as a Boolean array.

itasca.pebblearray.pos() → array float{pebble,2}.

Get a numpy array of the pebble location.

itasca.pebblearray.radius() → array float{ball}.

Get a numpy array of the pebble radii.

itasca.pebblearray.set_extra(slot: int, data: array float{pebble} or float{pebble}) → None.

Set the pebble extra data in the given slot with an array. Extra variables set by array must be of type float or vec.

itasca.pebblearray.set_group(membership: array bool{pebble}, group_name: str, slot=1) → None.

Set pebble group from an array. Where membership True set the corresponding pebble to be a member of group group_name in the given slot.

itasca.pebblearray.set_pos(data: array float{pebble, 2}) → None.

Set the pebble location from an array.

itasca.pebblearray.set_radius(data: array float{ball}) → None.

Set the pebble radii from an array.

itasca.pebblearray.vel() → array float{pebble,2}.

Get a numpy array of the pebble velocity.
