Keyword Phrase

Description

SPECIFY THE INITIAL CONDITIONS

Title of keyword block used to specify the ambient temperature and the temperature of the reactor components at the beginning of the simulation. For steady-state solution, these temperatures are used as initial guesses, while for transient simulation they are the initial conditions. Requires END statement to close keyword block.

TEMPERATURE OF WAFERS =

Provides the initial temperature of the wafers in the reactor load. Part of the SPECIFY THE INITIAL CONDITIONS keyword block.

Example: TEMPERATURE OF WAFERS = 600.0

Units: K

TEMPERATURE OF HEATERS =

Provides the initial temperature of the heaters for the reactor. Part of the SPECIFY THE INITIAL CONDITIONS keyword block.

Example: TEMPERATURE OF HEATERS = 600.0

Units: K

TEMPERATURE OF INSULATION =

Provides the initial temperature of the insulation for the reactor. Part of the SPECIFY THE INITIAL CONDITIONS keyword block.

Example: TEMPERATURE OF INSULATION = 400.0

Units: K

TEMPERATURE OF END CAPS =

Provides the initial temperature of the end caps of the reactor. Part of the SPECIFY THE INITIAL CONDITIONS keyword block.

Example: TEMPERATURE OF END CAPS = 600.0

Units: K

TEMPERATURE OF QUARTZ =

Provides the initial temperature of the quartz tubes in the reactor. Part of the SPECIFY THE INITIAL CONDITIONS keyword block.

Example: TEMPERATURE OF QUARTZ = 600.0

Units: K

AMBIENT TEMPERATURE =

Provides the ambient temperature around the reactor. Part of the SPECIFY THE INITIAL CONDITIONS keyword block.

Example: AMBIENT TEMPERATURE = 300.00
