Example

from hwx import inspire
from hwx.inspire import motion

model = inspire.newModel()
model.createSolidBlock()
a = motion.AngularInitialCondition(parts = model.parts)
i = motion.TranslationalInitialCondition(parts = model.parts)
model.gravityMagnitude = 0

analysis = motion.MbdAnalysis()
analysis.analyze(dtout=1/5)
inspire.fitView()

property magnitude#: Specifies the magnitude of the initial velocity.

property referenceFrame#

Specifies a reference system.

Positionable: The position of the initial condition is set using the Move tool.
System: The direction is dictated by the selected local system.

property parts#: List of parts for which initial conditions are specified.

property rigidGroups#: List of rigid group which initial conditions are specified.

property location#: Specifies the location of the initial condition object.

property direction#: Specifies the direction of the initial condition object..

property velocity#: Returns and sets the initial velocity of the object.

property position#: Specifies the position of the initial condition object.

property movable#

Specifies if the object can be moved using the move tool.

If yes then getting/setting the object.position must be implemented.

Can be True, False or a subset of “TX TY TZ RX RY RZ”.

snapToCG()#: Snaps the initial condition object to first part’s center of gravity.
