Comments

  1. The initial state for spring may be defined by more than one block (for the same spring type only).
  2. The relative force between pulley branches, DFS, is available only for spring property /PROP/TYPE12 (SPR_PUL).
  3. Spring velocity filtering, DV, is available only for spring property TYPE26. It is based on strain rate filtering factor (ALPHA – see /PROP/TYPE26 (SPR_TAB)).
  4. The nvars is the number of the first user variables to be initialized for a spring. It must be less or equal to the total number of internal variables used in a user type law (NUVAR).
