Adams/Solver
Input Arguments
alpha A double-precision variable that specifies the value of the independent
parameter a which CURSUB uses to evaluate a curve. Adams/Solver
restricts a to be:
Greater than or equal to the MINPAR value on the CURVE statement (-1.0
by default).
Less than or equal to the MAXPAR value on the CURVE statement (1.0 by
default).
id An integer variable that provides the identifier of the CURVE statement,
which requests information from the CURSUB. Adams/Solver
automatically derives additional information (such as the par argument)
from the identifier of the corresponding statement.
iflag A logical variable that Adams/Solver sets to TRUE. for the initial call to
CURSUB. In general, you do not need to check this flag in the subroutine.
However, you can check it if computations occur that require evalution at the
beginning of the simulation. In this case, if iflag is true, then the subroutine
should evaluate the computations.
iord An integer variable that specifies the order of the derivative that CURSUB
returns. The possible values are:
zero (return curve coordinates)
one (return first derivatives with respect to a)
two (return second derivatives with respect to a).
npar An integer variable that indicates the number of constants specified in the
USER parenthetical list. The primary purpose of npar is to provide the
CURSUB evaluation subroutine with the number of values stored in the par
array.
par A double-precision array of constants that is taken in order from the USER
parenthetical list of the CURVE statement.
