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)

  
node_ID Node identifier group to which boundary conditions are applied.
