Comments
- The unit keyword works in conjunction with the Input Units System. An Input Units System (keyword: /BEGIN) has to be defined in the input deck.
- A unit factor must be defined for mass, length and time.
- Supported codes are defined under the /BEGIN table.
- Local units system is optional and it is compatible with all the field unit_ID at the end of the keyword line (example, /MAT/LAW50/mat_ID/unit_ID).
- Each of the keywords listed
above can be input in its own unit system, which will then be
converted to the Input Units System of the input deck, using the
multiplying factors that are provided in this format.For example:
Global unit for mass defined in kg_m_s: /BEGIN/ EXAMPLE_UNIT #---1----|----2----|----3----|----4----|----5----|----6----|----7----|----8----|----9----|---10----| /BEGIN EXAMPLE_UNIT 140 0 kg m s kg m s #---1----|----2----|----3----|----4----|----5----|----6----|----7----|----8----|----9----|---10----| Local unit for mass for a particular option defined in g_m_s: #---1----|----2----|----3----|----4----|----5----|----6----|----7----|----8----|----9----|---10----| /UNIT/1 Unit_grams # MUNIT LUNIT TUNIT g m s #---1----|----2----|----3----|----4----|----5----|----6----|----7----|----8----|----9----|---10----| Use of defined local units for a particular option. In this example use this local unit for /ACCEL with unit_ID=1: #/ACCEL/accel_ID/unit_ID /ACCEL/1/1
