Welcome to Adams/Solver Subroutines - Kxcad.net

Prerequisite
Welcome to Adams/Solver Subroutines
Require input values, which must be obtained by a previous call to the dimension query utility
subroutines.
Calling Sequence
CALL GSE_X(X,NS)
CALL GSE_XDOT(XDOT,ND)
CALL GSE_XD(XD,ND)
CALL GSE_U(U,NI)
Input Arguments
NS Integer - the number of continuous states (used for validation)
ND Integer - the number of discrete states (used for validation)
NI Integer - the number of outputs (used for validation)
Output Arguments
X Double-precision array of dimension NS, the continuous states
XDOT Double-precision array of dimension NS, the time derivative of the
continuous states (IMPLICIT GSE only)
XD Double-precision array of dimension ND, the discrete states
U Double-precision array of dimension NI, the inputs
Caution: • If the incorrect validation integer value is provided, Adams/Solver (C++) will stop
with an error message.
Partial derivative entry utility subroutines: GSEPAR_X, GSEMAP_XDOT, GSEPAR_U
The partial derivative entry utility subroutines are used to provide Adams/Solver with:
• The partial derivative of the GSE_DERIV and GSE_OUTPUT with respect to the continuous
states, X
• The time derivative of the continuous states, XDOT (implicit GSE only)
• The inputs, U
• Calls to GSE_XDOT are only appropriate for GSE elements defined with the
IMPLICIT attribute and should only be made from the GSE_DERIV user
subroutine, not from GSE_OUTPUT.
