Comments
- The initial state for spring may be defined by more than one block (for the same spring type only).
- The relative force between pulley branches, DFS, is available only for spring property /PROP/TYPE12 (SPR_PUL).
- 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)).
- 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).
