Constant Boundary Conditions |
|
Constant boundary conditions are used to define time invariant constraints. They are defined in terms of a node number (or series of numbers), degree of freedom and (optionally) displacement. An option is provided to specify whether the boundary condition is absolute or relative. By default (absolute), the node is fixed with respect to its initial position. Alternatively, the relative option means the node is fixed with respect to its position at the end of the preceding analysis, rather than the initial position.
•*BOUNDARY is used to define boundary conditions. Specifically, the TYPE=CONSTANT input is used to define constant or time invariant boundary conditions.
