Enumeration Type Documentation

enum fld::Index

Identifiers of all known grid functions (the variables or fields on a grid).

Enumerator:

P
Q
R
S
L	Evolved variables.
P_t
Q_t
R_t
S_t
L_t	Time derivatives of the evolved variables.
C	Constraint violation.
gowdyLast	The total number of grid functions.

Definition at line 49 of file gowdy-solver.cpp.

    {
        P = GFCNT, Q, R, S, L,      //!< Evolved variables
        P_t, Q_t, R_t, S_t, L_t,    //!< Time derivatives of the evolved variables
        C,                          //!< Constraint violation
        gowdyLast                   //!< The total number of grid functions
    };

enum fld::sysIndex

Identifiers of all known grid functions (the variables or fields on a grid).

We distinguish:

• variables involved in time (these must also have the evolution RHS *_t),

• derived/temporary variables that store intermediate values, e.g., R = fB/gB

• purely output variables used for analysis and diagnostics, e.g., gHorz.

Enumerator:

t
r	Coordinates.

Definition at line 65 of file gridFunctions.h.

    {
        t = 0, r,  //!< Coordinates
        sysLast    //!< Used as the size marker
        #define GFCNT fld::sysLast
    };
