Fields
 NameDescription
Protected field_AbsTol An absolute error tolerance parameter
(Inherited from xOdeBase)
Protected field_AbsTolArray An absolute error tolerance parameter(array of length NEQ)
(Inherited from xOdeBase)
Protected field_Errors Array containing the exception messages.
(Inherited from xOdeBase)
Protected field_IDID REPORTS ON SUCCESSFULNESS UPON RETURN: IDID= 1 COMPUTATION SUCCESSFUL, IDID= 2 COMPUT. SUCCESSFUL (INTERRUPTED BY SOLOUTR) IDID=-1 INPUT IS NOT CONSISTENT, IDID=-2 LARGER NMAX IS NEEDED, IDID=-3 STEP SIZE BECOMES TOO SMALL. IDID=-4 PROBLEM IS PROBABLY STIFF (INTERRUPTED).
Protected field_InvokeInitializeODEs Indicated if the InitializeODEs method need to be invoked.
(Inherited from xOdeBase)
Protected field_InvokeSetInitialValues Indicated if the SetInitialValues method need to be invoked.
(Inherited from xOdeBase)
Protected field_IOut SWITCH FOR CALLING THE SUBROUTINE SOLOUTR: IOUT=0: SUBROUTINE IS NEVER CALLED IOUT=1: SUBROUTINE IS USED FOR OUTPUT. IOUT=2: DENSE OUTPUT IS PERFORMED IN SOLOUTR (IN THIS CASE WORK(5) MUST BE SPECIFIED)
Protected field_IPar User-specified array used to communicate integer parameter
(Inherited from xOdeBase)
Protected field_ITolAdamsGears For AdamsMoulton and OdeGearsBDF: MeITol = An indicator for the type of error control. ITOL RTOL ATOL EWT(i) MeITol =1 scalar scalar RTOL*ABS(Y(i)) + ATOL MeITol =2 scalar array RTOL*ABS(Y(i)) + ATOL(i) MeITol =3 array scalar RTOL(i)*ABS(Y(i)) + ATOL MeITol =4 array array RTOL(i)*ABS(Y(i)) + ATOL(i)
(Inherited from xOdeBase)
Protected field_ITolRK For Runge-Kutta ITol = An indicator for the type of error control. ITOL=0: BOTH RTOL AND ATOL ARE SCALARS. ITOL=1: BOTH RTOL AND ATOL ARE VECTORS.
(Inherited from xOdeBase)
Protected field_IWork MeIWork= An integer work array.
(Inherited from xOdeBase)
Protected field_Liw MeLiw= the length of the array IWORK
(Inherited from xOdeBase)
Protected field_Lrw MeLrw= The length of the array RWORK
(Inherited from xOdeBase)
Protected field_NEquations The number of equations
(Inherited from xOdeBase)
Protected field_RelTol A relative error tolerance parameter. The input parameters ITOL, RTOL, and ATOL determine the error control performed by the solver. The solver will control the vector e = (e(i)) of estimated local errors in Y, according to an inequality of the form rms-norm of ( e(i)/EWT(i) ) .le. 1, where EWT(i) = RTOL(i)*abs(Y(i)) + ATOL(i),
(Inherited from xOdeBase)
Protected field_RelTolArray A relative error tolerance parameter, either a scalar or an array of length NEQ.
(Inherited from xOdeBase)
Protected field_RPar User-specified array used to communicate real parameters
(Inherited from xOdeBase)
Protected field_RWork MeRWork= A real working array (double precision)
(Inherited from xOdeBase)
Protected field_Solution The array containing the solution of the ODEs [T, Y1,Y2,...]
Protected field_T0 The initial independent variable value.
(Inherited from xOdeBase)
Protected field_Y Array used to set the initial values and to return the solution in some ODE solvers. This array must be initialized equal to the initial values in the first call.
(Inherited from xOdeBase)
Protected field_Y0 The initial conditions.
(Inherited from xOdeBase)
