The Propagation Panel

Window title:
Propagation
Function:
The Propagation Panel allows the user to select and control the algorithms to use to compute trajectories.
Description:
The Propagation Panel is opened by selecting the Propagation window button located on the Orbits Panel. The Propagation Panel contains information necessary to control the forward and backward propagation of trajectories. When the Orbits Panel is dismissed, the Propagation Panel also vanishes.
Panel items:
The panel items on the Propagation Panel will depend on the method of propagation chosen. The top portion of the panel consists of 12#12 stack settings from which the user may select algorithms used by the propagator. The lower left section of the panel consists of 13#13 integer fields which are used to control integer parameters of the algorithms chosen. The maximum number of Newton iterations used in estimating an inverse image for a diffeomorphism is one example of an integer parameter. The lower right section of the panel contains a list of 14#14 double precision fields which are used to control floating point parameters of the chosen numerical algorithms. These fields may be used, for example, to set the minimum step size allowable for variable-step integrators, or to establish convergence criteria for Newton's method.

If a user wishes to install propagation algorithms (such as a special-purpose integrator) then the user will also want to adapt this panel to his or her needs. The Reference Manual shows how this is done.

We now describe the options for fixed-step integration algorithms:

We now describe the Propagation panel as it appears for mappings:
