Class FieldDSSTTesseralContext<T extends CalculusFieldElement<T>>

  • Type Parameters:
    T - type of the field elements
    public class FieldDSSTTesseralContext<T extends CalculusFieldElement<T>>
extends FieldForceModelContext<T>
    This class is a container for the common "field" parameters used in DSSTTesseral.

    It performs parameters initialization at each integration step for the Tesseral contribution to the central body gravitational perturbation.
