NumericalPropagatorDefinitionComputeInitialConditionsOnCreation Property

Gets or sets a value indicating whether propagators created by this definition will have the initial conditions of their highest derivatives and auxiliary elements computed in their CurrentState just after creation.

This is set to by default, however in some advanced use cases part of the propagation state is parameterized separately from the main propagator and not available for evaluation during the propagation creation process.

If you are receiving exceptions from invalid parameterization during propagator creation setting this to is a possible fix. In that case right after the NumericalPropagator is created its CurrentState will have the correct initial state values that were specified during the initialization of the state elements. However, the indices representing the auxiliary elements, or the highest derivative information of the state elements if applicable, will read 0.0 instead of their actual value. Once propagation begins, or Reset is called the state array will have the correct values.
