Enum Constant Details

EULER

public static final TimeIntegrator.Method EULER

First-order forward Euler.

RK2

public static final TimeIntegrator.Method RK2

Second-order Runge-Kutta (Heun).

RK4

public static final TimeIntegrator.Method RK4

Classical 4th-order Runge-Kutta.

SSP_RK3

public static final TimeIntegrator.Method SSP_RK3

Strong Stability Preserving RK3.

IMEX_PRESSURE_CORRECTION

public static final TimeIntegrator.Method IMEX_PRESSURE_CORRECTION

IMEX (Implicit-Explicit) pressure correction method. Treats transport (advection) explicitly and the pressure wave equation implicitly, removing the acoustic CFL constraint. Allows time steps 10-100x larger than fully explicit schemes for long pipelines. Based on the pressure-correction approach of Harlow and Amsden (1971) adapted for two-fluid models.

Method Details

values

public static TimeIntegrator.Method[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static TimeIntegrator.Method valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
