R | Absolute zero-point |
The absolute zero-point is used by the radiation boundary conditions
(!RADIATE / !SRADIATE in the control file)
to convert the input temperatures into absolute temperatures.
Specify the value according to the unit of the input temperatures.
| Unit of input temperature | ZERO |
|---|---|
| Celsius (°C) | -273.15 (default) |
| Kelvin (K) | 0.0 |
| Fahrenheit (°F) | -459.67 |
The other input values, such as the radiation factor, must be given in the same unit system as the input temperatures.
Note:
- Omissible. Becomes "absolute zero-point = -273.15", that is, input temperatures in Celsius, when omitted.
- When the input temperatures are in Kelvin, "
!ZERO" must be defined as0.0.- When "
!ZERO" is not defined, a warning message is displayed to report that the default value is used.- When "
!ZERO" is defined multiple times, the contents will be updated and a warning message will be displayed.
