This boundaryĬondition is identical to applying a boundary condition using the direct format If a nodal transformation has been applied at these nodes). Of symmetry that is normal to the X-axis (which will be ( Pipes and pipebends with deforming cross-sections: elbow elements).įor example, applying a boundary condition of typeĮDGE indicates that the node set lies on a plane NODEFORM types apply only to elbow elements Prevent all cross-sectional deformation (warping, ovalization, and uniform Prevent ovalization of an elbow section at a node. Prevent warping of an elbow section at a node. Generally not be used in problems involving finite rotations. Therefore, antisymmetry boundary conditions should Otherwise, the prescribed rotation at the node may notīe what you expect. When boundary conditions are prescribed at a node in anĪnalysis involving finite rotations, at least two rotation degrees of freedom The following boundary condition types are available only inĪntisymmetry about a plane with X = constantĪntisymmetry about a plane with Y = constantĪntisymmetry about a plane with Z = constant Pinned (degrees of freedom 1, 2, 3 = 0). The following boundary condition “types” are available in bothįully built-in (degrees of freedom 1, 2, 3, 4, 5, 6 = 0). The type of boundary condition can be specified instead of degrees ofįreedom.
