156 Adams/Solver The DIFSUB evaluation subroutine computes a differential-equation value for a DIFF statement (C++ or FORTRAN). DIFSUB is optional. You only need it if you don't want to use a function expression in the DIFF statement. Use Corresponding Statement Calling Sequence SUBROUTINE DIFSUB (id, time, par, npar, dflag, iflag, value)
Input Arguments Welcome to Adams/Solver Subroutines dflag A logical variable that Adams/Solver sets to true when it calls DIFSUB to evaluate partial derivatives of the function. Otherwise, Adams/Solver sets dflag to false. id An integer variable that provides the identifier of the DIFF statement requesting information from the DIFSUB. From the identifier, Adams/Solver automatically knows other information (such as the par argument) available in the corresponding statement. iflag A logical variable that Adams/Solver sets to true when it needs the functional dependency of the user-defined variable. The functional dependencies are set with the same calls to the SYSARY and SYSFNC utility subroutines that are made to compute the value of the user-defined variable. If iflag is false, Adams/Solver computes the value of the userwritten variable. 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 DIFSUB evaluation subroutine with the number of values stored in the par array. par A double-precision array of constants taken in order from the USER parenthetical list of the DIFF statement. time A double-precision variable through which Adams/Solver conveys the current simulation time. Output Argument value A double-precision variable that returns the value of the differential equation. If the equation is in the explicit form, value contains the derivative. If the equation is in the implicit form, value contains the residual (that is, the error relative to zero) of the implicit equation. In this case, value can be a function of the dependent variable and its time derivative. Extended Definition A DIFF statement with a function expression is sufficient for defining most user-defined differential equations. However, if the expression becomes lengthy and awkward or if the definition of the equation requires additional features of FORTRAN-77, you should use the FUNCTION=USER() argument in the DIFF statement, and write a DIFSUB evaluation subroutine to define the differential equation. DIFSUB allows you to define a differential equation for a variable either explicitly or implicitly: • In an explicit definition, the derivative of the variable is evaluated on the right side of a FORTRAN-77 assignment statement. 157
