Initial Conditions Card (HYDT-KE)

Initial conditions are used to set the starting thermodynamic state of the system at every grid cell. Initial conditions can be specified via the user input or from a restart file. Restart files contain a record of all primary variables and phase condition for every grid cell. Because STOMP-HYDT-KE allows for nonequilibrium conditions between the  mobile- and hydrate formers, initial conditions can be specified as being in thermodynamic equilibrium or in a non-equilibrium state. To limit the number of combinations of variables used to define the state of the system, 7 initial condition options were developed. Flash calculation routines are used to convert the initial condition specification to one of the 16 phase conditions.

• General concepts about phase conditions specified by initial conditions are provided on the Card Description page.

• Input options for the 7 initial conditions are provided on the Card Options (HYDT-KE) page.

• Formatting instructions for specifying initial conditions are provided on the Card Syntax (HYDT-KE) page.

• Examples of initial condition cards for STOMP-HYDT-KE are provided on the Card Examples (HYDT-KE) page.
