  1. Altair Simulation FEA pre-processors must be used to generate the encryption keyid and strings.
  2. keyid uses the format %AB123.

    Where, AB= any 2 letters and 123=any 3 numbers, such as %TY583.

  3. The keyid is repeated at the beginning of header strings 2 – 5.
  4. /ENCRYPT and /KEY cannot use the same keyid in the same model.
  5. The following entities can be encrypted in the model:
    • Any material (/MAT/...)
    • Any failure model (/FAIL/...)
    • Any viscous model (/VISC/...)
    • Any equation of state (/EOS/...)
    • Any property (/PROP/...)
    • Functions /FUNCT and /FUNCT_SMOOTH
