Comments

  1. 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.
  2. A unit factor must be defined for mass, length and time.
  3. Supported codes are defined under the /BEGIN table.
  4. Local units system is optional and it is compatible with the following keywords:

    material law types: 0, 1, 2, 3, 4, 5, 6, 10, 11, 14, 15, 19, 21, 22, 23, 24, 25, 27, 28, 32, 33, 34, 35, 36, 37, 38, 40, 41, 42, 43, 44, 46, 48, 49, 50, 51, 52, 53, 54, 57, 58, 59, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 87, 88, 90, 92, 93, 94, 95, 97, 100, 101, 103, 104, 106, 108, 113, 187 and also /HEAT/MAT

    property types: 0, 1, 2, 3, 4, 6, 8, 9, 10, 11, 12, 13, 14, 16, 17, 18, 19, 20, 21, 22, 23, 25, 26, 28, 32, 33, 35, 36, 43, 44, 45, 46, 51, /PCOMPP, /STACK and /PLY

    interface types: 2, 3, 5, 6, 7, 8, 10, 11, 14, 15, 16, 17, 19, 20, 21, 23, 24 and 25
       

    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
