Block Format Keyword
/BEGIN - Run Name
Description
Sets the run name, the version of the input manual, the number of Starter run and input and work unit systems.
This option is required.
Work unit system and Input unit system are used instead of unit system defined previously in: /UNIT/name for input format prior to v10.0.

Run identification name
(Character, maximum 80 characters)
|
Invers
|
Version of the input manual
(for example, Invers=100 for version 10, Invers=110 for version 11)
(Integer > 100)

Irun
|
Number of Starter run
(Integer)
|
Input_mass_unit
|
Unit system of input for mass
Default = Work_mass_unit (Real) or code
|
Input_length_unit
|
Unit system of input for length
Default = Work_length_unit (Real) or code
|
Input_time_unit
|
Unit system of input for time
Default = Work_time_unit (Real) or code
|
Work_mass_unit
|
Unit system used for calculation for mass
(Real) or code

| 1. | To be taken into account, this option must be written after the mandatory keyword #RADIOSS Starter. |
| 2. | The Runname is defined by the first non-blank character. It may have a maximum of 80 characters and a minimum of four characters. The characters "/" and "\" are not allowed. |
| 3. | The Input unit system defines the unit of the input deck. The work unit system defines which unit has been used during the computation. If the Input unit system is not equal to work unit system, RADIOSS will convert the input unit system (in Starter file, not in Engine file) to work unit system automatically. |
| 4. | The Work unit system defines the unit in which the calculation is done. The output is defined in the work unit system. |
| 5. | In submodels, Work unit system defined in /BEGIN of a submodel is ignored: the Work unit system defined in the main /BEGIN card is used. |
| 6. | If an Input unit system is not defined, Input unit system is equal to work unit system. |
| 7. | A code defining a unit is composed of a prefix giving the multiplying factor and a suffix giving the corresponding SI unit (kg for mass, m for length, and s for time): |

| 8. | RADIOSS does not have a built-in unit system, so it is very important to keep unit consistency in your model. |
| 9. | As an alternative to the unit code, it is possible to input its value instead. |
