PropagationNewtonianPoint Properties

Gets the number of parameters (per Order) within this element.

Gets or sets the string identifying this instance in the overall output.

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.

Gets or sets the initial position.

Gets or sets the initial velocity.

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.

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.

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.

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.

Gets the order of the differential equation corresponding to this element.

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.
