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
