Antisymmetry about a plane with Y = constant (U1 = U3 = UR2 = 0;Abaqus/Standard only). ZASYMM: Antisymmetry about a plane with Z = constant (U1 = U2 = UR3 = 0;Abaqus/Standard only). PINNED: Pinned (U1 = U2 = U3 = 0). ENCASTRE: Fully built-in (U1 = U2 = U3 = UR1 = UR2 = UR3 = 0).A list of the boundary conditions used in ABAQUS. U1, U2 and U3 specify movements along Table 1. UR2 and UR3 specify rotation about the x, y and z axes, respectively.
Toggle on the buttons labeled U1, U2, and U3 to constrain the end of the hinge in the 1-, 2-, and 3-directions. You do not need to constrain the rotational degrees of freedom of the hinge because solid elements (which have only translational degrees of freedom) will be used to mesh the hinge.ABAQUS Scripting Reference Manual u1. A Float, a Complex, or a SymbolicConstant specifying the displacement component in the 1-direction. Note: Although u1, u2, u3, ur1, ur2, and ur3 are optional arguments, at least one of them must be specified. u2. A Float, a Complex, or a SymbolicConstant specifying the displacement component in the To edit an existing base motion boundary condition using menus or managers, see Editing step-dependent objects. In the Basic tab, select the Degree-of-freedom to specify the direction for which the base motion is being defined. This direction is always a global direction: U1, U2, U3, UR1, UR2, or UR3. .
