Ode |
The OdeImplicitRungeKutta5 type exposes the following members.
Fields| Name | Description | |
|---|---|---|
 | CONRA5 | |
| INTERN | |
| LINAL | |
| MeH | INITIAL STEP SIZE GUESS; FOR STIFF EQUATIONS WITH INITIAL TRANSIENT, H=1.D0/(NORM OF F'), USUALLY 1.D-3 OR 1.D-5, IS GOOD. THIS CHOICE IS NOT VERY IMPORTANT, THE STEP SIZE IS QUICKLY ADAPTED. (IF H=0.D0, THE CODE PUTS H=1.D-6). |
| MeIJAC | SWITCH FOR THE COMPUTATION OF THE JACOBIAN: IJAC=0: JACOBIAN IS COMPUTED INTERNALLY BY FINITE DIFFERENCES, SUBROUTINE "JAC" IS NEVER CALLED. IJAC=1: JACOBIAN IS SUPPLIED BY SUBROUTINE JAC. |
| MeIMAS | GIVES INFORMATION ON THE MASS-MATRIX: IMAS=0: M IS SUPPOSED TO BE THE IDENTITY MATRIX, MAS IS NEVER CALLED. IMAS=1: MASS-MATRIX IS SUPPLIED. |
| MeMLJAC | SWITCH FOR THE BANDED STRUCTURE OF THE JACOBIAN: MLJAC=N: JACOBIAN IS A FULL MATRIX. THE LINEAR ALGEBRA IS DONE BY FULL-MATRIX GAUSS-ELIMINATION. 0.LE.MLJAC.LT.N: MLJAC IS THE LOWER BANDWITH OF JACOBIAN MATRIX (.GE. NUMBER OF NON-ZERO DIAGONALS BELOW THE MAIN DIAGONAL). |
| MeMLMAS | SWITCH FOR THE BANDED STRUCTURE OF THE MASS-MATRIX: MLMAS=N: THE FULL MATRIX CASE. THE LINEAR ALGEBRA IS DONE BY FULL-MATRIX GAUSS-ELIMINATION. 0.LE.MLMAS.LT.N: MLMAS IS THE LOWER BANDWITH OF THE MATRIX (.GE. NUMBER OF NON-ZERO DIAGONALS BELOW THE MAIN DIAGONAL). MLMAS IS SUPPOSED TO BE .LE. MLJAC. |
| MeMUJAC | UPPER BANDWITH OF JACOBIAN MATRIX (.GE. NUMBER OF NON- ZERO DIAGONALS ABOVE THE MAIN DIAGONAL). NEED NOT BE DEFINED IF MLJAC=N. |
| MeMUMAS | UPPER BANDWITH OF MASS-MATRIX (.GE. NUMBER OF NON- ZERO DIAGONALS ABOVE THE MAIN DIAGONAL). NEED NOT BE DEFINED IF MLMAS=N. MUMAS IS SUPPOSED TO BE .LE. MUJAC. |
