bcs_ID Boundary conditions block identifier.

(Integer, maximum 10 digits)

  
bcs_title Boundary condition block title.

(Character, maximum 100 characters)

  
Trarot Codes for translation and rotation.
= 0
Free DOF
= 1
Fixed DOF

(6 Booleans)

Example: 101 111 means the x and z translations, as well as all rotations are fixed; the y translation is free.

  
Skew_ID Skew identifier.

If not zero, the boundary conditions are applied with respect to this local skew.

(Integer)

  
grnd_ID Identifier of the node group on which boundary conditions are applied.

(Integer)

Comments

  1. The grnd_ID input is obligatory. The boundary conditions will be applied only on nodes that belong to a node group.
  2. Input format details for the field Trarot are shown above. The six individual codes (one per direction) must be right justified in the ten character fields used by the variable Trarot.
