## PropagationNewtonianPoint Properties |

The PropagationNewtonianPoint type exposes the following members.

Properties

Name | Description | |
---|---|---|

AppliedForces | Gets a list of the forces applied at the IntegrationPoint. The Kind of force will determine whether a given force will be divided by mass in order to compute the Newtonian acceleration of the IntegrationPoint. Inertial acceleration = AppliedForce / Mass + AppliedSpecificForce + AppliedReactionForce | |

Dimension |
Gets the number of parameters (per Order) within this element.
(Overrides PropagationStateElementDimension.) | |

Identification |
Gets or sets the string identifying this instance in the overall output.
(Inherited from PropagationStateElement.) | |

IncludeHighestDerivativeInOutput |
Gets or sets a value indicating whether to include the derivative computed at each step with the output.
If this is true, the output converted from the raw state will contain the derivative
associated with the Order of the differential equation.
(Inherited from PropagationStateElement.) | |

InitialPosition |
Gets or sets the initial position.
| |

InitialVelocity |
Gets or sets the initial velocity.
| |

IntegrationFrame |
Gets or sets the inertial ReferenceFrame in which the position, velocity, and forces are defined.
Note that the AppliedForces should all be inertial forces, even if they are expressed with
different Axes which may be rotating with respect to each other. For instance, drag may be expressed
using Earth fixed axes while gravity is given in Earth inertial axes but both are inertial forces.
No fictitious forces will be added or removed from them due to differences in reference frames.
By default, the integration frame is set to the InertialFrame of the Earth.
(Overrides PropagationPointElementIntegrationFrame.) | |

IntegrationPoint |
Gets a Point which is parameterized on the position and velocity in the state during integration.
This point is only valid while the NumericalPropagator is running.
For more general use, a PointInterpolator should be created from the
NumericalPropagationStateHistory produced by the propagator.
(Overrides PropagationPointElementIntegrationPoint.) | |

IsFrozen |
Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an
ObjectFrozenException will be thrown if an attempt is made to do so.
(Inherited from DefinitionalObject.) | |

Mass |
Gets or sets the total point mass of the body on which the forces are applied.
This is the mass used in Newton's second law to determine the equations of motion.
Note that no derivatives of mass will be included. To include reaction forces associated
with changes in mass, this scalar should correctly model the change in mass over time
and the reaction force should be added to AppliedForces based on this mass.
| |

Order |
Gets the order of the differential equation corresponding to this element.
(Overrides PropagationStateElementOrder.) | |

StateParameter |
Gets or sets a parameter which represents the state during propagation. In general,
users should never need to explicitly set this property. It should only be set
when multiple NumericalPropagator objects are running in the same EvaluatorGroup,
such as when elements of a state require additional instances of a NumericalPropagator
inside their implementation in order to produce their values. In such cases, it may
be necessary to distinguish between the state of the exterior propagator and the
state of the interior propagator. In these cases, it is up to the user to ensure
that both the state and all of its elements are configured with the same parameter.
Otherwise, the state will throw an exception when creating its propagator.
