Field

Contents

bcs_ID

Boundary conditions block identifier

(Integer, maximum 10 digits)

bcs_title

Boundary conditions block title

(Character, maximum 100 characters)

Trarot

Codes for translation and rotation

(6 Booleans)

= 0: free DOF

= 1: fixed DOF

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

Node group to which boundary conditions are applied

(Integer)

hmtoggle_plus1Comments
1.The grnd_ID input is obligatory. The boundary conditions will be applied only to nodes that belong to a node group.
2.Input format details for the Trarot field are shown above. The six individual codes (one per direction) must be right justified in the ten character fields used by the variable Trarot.
