This command is used to construct single-point homogeneous boundary constraints.
| fix $nodeTag (ndf $constrValues) |
| $nodeTag | integer tag identifying the node to be constrained |
| $constrValues | ndf constraint values (0 or 1) corresponding to the ndf degrees-of-freedom. |
| 0 unconstrained (or free) | |
| 1 constrained (or fixed) |
EXAMPLE:
fix 1 1 1 1 1 1 1; # node 1: fully fixed
fix 2 0 1 0 0 1 0 # node 2: homogeneous constraints (movement = 0) at dof 2 and 5 only.
