| Conversion
|
The conversion factor that converts the quantity from this unit to SI units. Read-only except for user-defined units.
|
| Description
|
The full name of the unit. Read-only except for user-defined units.
|
| Dimensions
|
The physical dimensions of the units. Read-only except for user-defined units.
|
| Offset
|
The offset factor used to convert the quantity from this unit to SI units. Used for Celsius and Fahrenheit temperatures. Read-only except for user-defined units.

Preferred
|
For each dimensional combination in use in the simulation,
Simcenter STAR-CCM+ marks exactly one unit to be the preferred unit for that dimension. For example the preferred unit for quantities with the dimension of length might be meters and the preferred unit for quantities with dimensions of length per time might be kph (kilometers per hour).
The preferred units are the ones that are used by default for any new physical quantity. You can change the preferred unit for an individual dimensional combination, and you can change the preferred units for all quantities to a standard system.
Although the preferred unit is used by default, you can override it at any time you like in specific situation. For example, you might have the preferred unit for dimensions of velocity to be the SI standard of meters per second, but for a specific velocity vector display you could change the units to kilometers per hour.
Note: Field functions default to SI units, without using to the
Preferred property.
|
| Ticked
|
Makes this unit the preferred one for these dimensions.
|
| Cleared
|
Causes the preferred unit for this dimension to revert back to the default for the current preferred system (SI or USCS).
|
| System
|
The systems (SI, USCS, or Other) to which this unit belongs. “s” (seconds), for example, is part of both SI and USCS. User-defined units belong to “Other”.
