/KEY

Block Format Keyword Radioss supports the /KEY option. This format is written by Altair simulation pre-processors.

Comments

  1. There are three distinct crypting algorithms available in Radioss, in all cases the crypting key is defined by the /KEY keyword. The choice of the algorithm is then determined by the key format:
    • Format %SXxxx
      • Reserved for Safety (dummy models, and so on), concern /MAT and /PROP cards
      • Need special safety license.
    • Format %FUxxx
      • Used for /FUNCT card crypting
      • No license needed
    • Other formats: %XXXX, %xxxx
      • Available for material and Property cards crypting via Altair simulation pre-processor
      • Using standard algorithm
      • No license needed

    The capital X may be replaced by any alpha-numeric character; a lower case x may be replaced by any number 0-9.

  2. The following entities can be encrypted in the model:
    • Any materials (/MAT/...)
    • Any failure models (/FAIL/...)
    • Any viscous models (/VISC/...)
    • Any equation of states (/EOS/...)
    • Any properties (/PROP/...)
    • Function/FUNCT/FUNCT_SMOOTH
    • Table /TABLE
