fix Command
This command is used to construct a number of single-point homogeneous boundary constraints.
fix $nodeTag (ndf $constrValues)
| Argument | Type | Description |
|---|---|---|
| $nodeTag | [in teger]{.t itle-ref} | unique tag identifying the node to be constrained |
| $con strValues | ndf constraint values (0 or 1) corresponding to the ndf degrees-of-freedom. 0 unconstrained (or free) 1 constrained (or fixed) |
Example:
The following examples demonstrate the commands in a script to add homogeneous boundary conditions
to nodes 1 and 2 for a model with ndf of 6. Node 1 is specified to be totally fixed, node 2 is only constrained in the second and fifth degree-of-freedom.
