Constructor Detail

AbstractRKData

public AbstractRKData(PsimuPropagationData propData,
              double timestep)
               throws PsimuException

Creates a new instance.

Parameters:

propData - propagation data

timestep - timestep (s)

Throws:

PsimuException - If propagation data is not give a PsimuException is thrown.

Method Detail

getTimeStep

public double getTimeStep()

Get Integrator timestep.

Returns:

timestep (s).

getAbsMassTolerance

public double getAbsMassTolerance()

Get the absolute mass tolerance.

Specified by:

getAbsMassTolerance in class AbstractNumericalIntegratorData

Returns:

the absolute mass tolerance

getRelMassTolerance

public double getRelMassTolerance()

Get the relative mass tolerance.

Specified by:

getRelMassTolerance in class AbstractNumericalIntegratorData

Returns:

the relative mass tolerance

getFirstOrderIntegrator

public abstract org.apache.commons.math3.ode.FirstOrderIntegrator getFirstOrderIntegrator(org.orekit.orbits.Orbit initialOrbit)

Get the first order integrator.

Specified by:

getFirstOrderIntegrator in class AbstractNumericalIntegratorData

Parameters:

initialOrbit - initial orbit for simplified tolerances computation. It might be null if complete tolerances were already given. (Only for DOP Integrator)

Returns:

the first order integrator
